Introduction Chapter 11
About the IOLAN
The IOLAN is an Ethernet communications/terminal server that allows serial devices to be connected directly to LANs. The IOLAN can connect to a wide range of devices including:

Terminals for multi-user UNIX systemsData acquisition equipment (manufacturing, laboratory, scanners, etc.)Retail point-of-sale equipment (bar coding, registers, etc.)PCs using terminal emulation Modems for remote access and Internet accessISDN adapters for branch remote access and Internet access

The performance and flexibility of the IOLAN allows you to use a wide range of high speed devices in complex application environments. The IOLAN products will work in any server environment running TCP/UDP/IP.

IOLAN Family ModelsThe IOLAN comes in several different models to meet your network needs:

DS—Offered as a 1-port unit (DB25M, DB25F, RJ45, and DB9M interfaces available), this model provides general IOLAN functionality and supports software configurable serial interface protocols EIA-232/422/485. TS—This model is available with two serial ports (RJ45 only) and supports EIA-232 only. The TS model is similar to the DS model supporting only general IOLAN functionality.SDS—This model is available in both desktop and rack mount configurations. Both models support software configurable serial interface protocols EIA-232/422/485. The SDS model has the advanced secure IOLAN feature set in addition to the general IOLAN functionality.STS—This model comes in one desktop model and several rack mount configurations. All models support EIA-232 only. The STS model has the advanced secure IOLAN feature set in addition to the general IOLAN functionality.SCS—This model comes in several rack mount configurations. All models support EIA-232 only and have an internal PCI card interface. The SCS model has the advanced secure IOLAN feature set in addition to the general IOLAN functionality.MDC—Offered as a 4-port and 8-port unit (RJ45 only), this model is a medical unit compliant with IEC 60601-1 and has galvanically isolated EIA-232 serial ports. The MDC model has the advanced secure IOLAN feature set in addition to the general IOLAN functionality.

See Hardware for information about the hardware specifications for your IOLAN model. See Software for a list of the basic and advanced software features.

Getting to Know Your IOLANThis section describes the hardware components found on your IOLAN unit.

OverviewAll IOLANs have the same basic hardware components to allow you to connect to serial devices, connect to the network, monitor LAN and serial activity, and manage the unit. Below is a list of these components:

Serial Port(s)—Connector(s) that will be used to connect to a serial device.Activity—This LED flashes to indicate LAN activity.Link10/100—This LED indicates the Ethernet connection speed for desktop models:– Green—10 Mbits– Yellow—100 Mbits– Off—no LAN connectionPower/Ready—This LED can cycle through several colors (yellow, green, red) during a boot process, but should complete with a green light. If the LED is green after power up but continues to cycle on and off (flashes green), this indicates that the console switch is in the on position. You can learn more about the Power/Ready LED in Hardware Problems .External Power Supply—This is an external AC power supply.Console/Serial Switch—This switch determines whether serial port 1 functions as a serial port or a console port. If you have an I/O model, you will see two console switches. Console/Serial Switch 1 is used to determine the console/serial setting for Port 1 and the Console/Serial Switch 2 is not used. Reset—The inset RESET button will reboot the IOLAN if pushed in and released quickly. It will reset the IOLAN to factory defaults if pushed in and held for more than three seconds.

Note: The maximum load for the Relay channel is 1A @ 30VDC or 0.5A @ 120VAC.

Console/Serial SwitchLocated at the back of the desktop IOLAN models is a switch that controls whether serial port 1 is in Console or Serial mode.

Look at your model to verify the direction of the ON switch position. ON indicates that serial port 1 is in Console mode; otherwise serial port 1 is in Serial mode.

Console ModeConsole mode is used when you have a direct connection between a serial device (like a terminal or a PC) and the IOLAN, accessed by the admin user to configure/manage the IOLAN. Console mode automatically sets serial port settings as:

Serial Interface to EIA-232Speed to 9600Flow Control to NoBits to 8Stop Bits to 1Parity to None

Console mode also displays extra system messages. Serial port 1 will ignore any Serial Port settings when in Console mode, so you need to turn Console mode off to use serial port 1 in your network.

Serial ModeSerial mode is used when the IOLAN acts as a communications server, or anytime you are not connecting directly to the IOLAN to configure it. You can connect directly to the IOLAN in Serial mode, but the IOLAN will not display all the messages/information you will get in Console mode.

Note: When the console switch is in the on position, the Power/Ready LED will blink green.


Powering Up the IOLAN

Powering Up the IOLANModels with Barrel Connector

To power up the IOLAN, perform the following steps:1. Plug the external power supply into the IOLAN and then into the electrical outlet.2. You will see the LEDs cycle for several seconds and then remain a solid green, indicating that it

is ready to configure/use.Before you start to configure the IOLAN, you should set the IOLAN jumpers if you want to terminate the line or use the power in pin feature (instead of an external power supply, if your desktop IOLAN model supports it).In some circumstances, the setting of jumpers may be required:

IOLAN DS models where EIA-422/485 line termination is required.IOLAN I/O models with Digital I/O for setting the channels as input or output.IOLAN I/O models with Analog I/O for setting Voltage/Current.

See Appendix C, "Setting Jumpers" to see how to set the jumpers for your IOLAN desktop model.

Models with Terminal Block ConnectorTo power up the unit, perform the following steps:1. Unplug the power plugable terminal block from the back of the unit.2. Loosen the screws and then insert your positive (+) wire into the left terminal and screw it down.

Insert the negative (-) wire into the right terminal and screw it down as shown below:

3. Plug the power terminal block back into the unit4. Plug the power supply into the electrical outlet.5. You will see the LEDs cycle for several seconds and then remain a solid green, indicating that it

is ready to configure/use.

Before you start to configure the IOLAN, you should set the IOLAN jumpers for Digital I/O (see Digital I/O Module ) or Analog Input (Analog Input Module ) channels.

Configuration Methods Chapter 33
Introduction
This chapter provides information about the different methods you can use to configure the IOLAN. Before you can configure the IOLAN, you must assign an IP address to the IOLAN. See the Getting Started to find out how to assign an IP address to the IOLAN.Once an IP address is assigned to the IOLAN, you can use any of the configuration methods to:

Configure users.Configure IOLAN system parameters.Configure serial port parameters.Configure network parameters.Configure time parameters.Reboot the IOLAN.Manage I/O channels (when applicable).View statistics while connected to the IOLAN.


Configuration Methods Overview

Configuration Methods OverviewSome of the IOLAN configuration methods have the capability of configuring an IP address, which is the first required configuration step for a new IOLAN. Once the IOLAN has been assigned an IP address, any of the configuration methods can be used to configure the IOLAN.

Configures an IP AddressFollowing is a list of methods for setting the IOLAN IP address and a short explanation of when you would want to use that method:

Easy Config Wizard—The Easy Config Wizard is available from the CD ROM included with your IOLAN. You can use the Easy Config Wizard to set the IOLAN’s IP address and configure serial ports. This configuration method would typically be used when:

All ports are to have the same configuration.Only the most commonly used profiles are required.Straightforward application with no advanced functionality required.Easy Config is installed on a Windows®-based PC with local network access to the IOLAN.

DeviceManager—Use this method when you can connect the IOLAN to the network and access the IOLAN from a Windows® PC. The DeviceManager is a Windows®-based application that can be used for IOLAN configuration and management. The DeviceManager can be used to assign an IP address and perform the complete configuration and management of the IOLAN.Direct Connection—Use this method when you can connect to the IOLAN from a serial terminal or from a computer running terminal emulation software over a serial port. Using this method, you will need to configure and/or manage the IOLAN using either the Menu or CLI.DHCP/BOOTP—Use this method when you have a BOOTP or DHCP server running and you can connect the IOLAN to your network. The IOLAN will automatically obtain an IP address from a local network DHCP/BOOTP server when this service is enabled (it is disabled by default). You can also configure certain IOLAN parameters that will be passed from the DHCP/BOOTP server to the IOLAN when it boots up. Other configurators such as DeviceManager, CLI, or Menu can be used to set this option, and obtain the initial IP address.ARP-Ping—Use this method when you can connect the IOLAN to the network and want to assign a temporary IP address to the IOLAN by adding an ARP entry to your PC and then pinging it.IPv6 Network—When the IOLAN is connected to an IPv6 network, its local link address is determined using stateless auto configuration.

Once an IP address has been assigned to the IOLAN, in most cases, you can continue to use the same method if it is a configurator or you can switch to any other configuration method.

Requires a Configured IP AddressThe following configuration methods require that an IP address already be assigned to the IOLAN.

WebManager—WebManager is a fully functional, browser-based configuration method.

Configuration Methods 31

Easy Config Wizard

Easy Config WizardThe Easy Config Wizard is a configuration wizard that will configure all the serial ports on your IOLAN to one of the following:

You can launch the Easy Config Wizard from the Perle website or from the installation CD-ROM.

The Easy Config Wizard has been designed to walk you through the configuration process for any of the available configuration options shown on the Welcome window.


DeviceManager

DeviceManagerOverview

The DeviceManager is a Windows®-based application that can be used to connect to the IOLAN to actively manage and configure it or can create new IOLAN configurations offline. See Chapter 5, Using DeviceManager and WebManager for information on configuring/managing the IOLAN with DeviceManager.

Access PlatformsThe DeviceManager can be run from Windows 2000®/Windows Server 2003®/Windows Server 2003 R2®/Windows XP®/Windows Vista®/Windows Server 2008®/Windows Server 2008 R2®/Windows 7®/Windows 8 ®and Windows Server 2012® platforms. DeviceManager can be installed from the product CD-ROM or downloaded from the Perle website. Unless the IOLAN has already been configured with a Gateway, DeviceManager can only access IOLANs in the local subnet. The DeviceManager can be accessed by only the admin user.

FeaturesDeviceManager supports the following features:

The ability to download the same configuration file to several IOLANs in one operation.The ability to save a configuration file locally in text format, in addition to the binary format.The ability to create a configuration file without being connected to the IOLAN.The ability to open a session to the IOLAN and download a (saved) configuration file to it.The ability to download custom files, such as new terminal definitions and a custom language files to the IOLAN.

Connecting to the IOLAN Using DeviceManagerBefore you can use DeviceManager, you need to install it on your Windows operating system from the IOLAN CD-ROM or you can download it from the Perle website. After the DeviceManager application is installed, click Start, All Programs, Perle, DeviceManager, DeviceManager to start the application. When you launch the DeviceManager, it will scan the network for IOLANs:


DeviceManager

All discovered IOLAN will be displayed on the list along with their name and IP address. When a new IOLAN is discovered on the network, that has not yet been assigned an IP address, it will be displayed with an IP Address of Not Configured. To configure the IP address, click on the IOLAN and then click the Assign IP button.

Choose the method you want to use to assign an IP address to the IOLAN:Type in the IP address that you want to assign to this IOLANEnable the Have the IOLAN automatically get a temporary IP Address option. This will turn on DHCP/BOOTP, so the IOLAN will attempt to get its IP address from your DHCP/BOOTP server. If you don’t have a DHCP/BOOTP server, DeviceManager will temporarily assign an IP address in the range of 169.254.0.1-169.254.255.255 that will be used only for the duration of the DeviceManager/IOLAN communication.

After you configure the IP address, click the Assign IP button.The refreshed list will now display the assigned IP address for the new IOLAN. To connect to the IOLAN, click the IOLAN entry and click OK. You will be asked to supply the Admin password (the factory default password is superuser).

If you have a successful connection, the DeviceManager will retrieve the configuration and then display the IOLAN’s System Information and you can begin configuring the IOLAN.

Note: The DeviceManager does not automatically update the IOLAN’s configuration. You must download the configuration changes to the IOLAN and then reboot the IOLAN to make the configuration changes take effect

Command Line Interface

Command Line InterfaceOverview

The Command Line Interface (CLI) is a command line option for IOLAN configuration/management. See the Command Line Interface Reference Guide for a full breakdown of all the CLI commands and their functionality.

Access PlatformsThe CLI is accessed by any application that supports a Telnet session to the IOLAN’s IP address, such as Putty, SecureCRT, or from a command prompt. You can also access the CLI from a dumb terminal or PC connected to a serial port.

FeaturesThe CLI supports the following features:

You can access the IOLAN from any application that supports Telnet.The ability to clear the ARP table (cache).The ability to save a configuration file locally in text format, in addition to the binary format.

Connecting to the IOLAN Using the CLIThere are two ways you can access the IOLAN, through the network (Ethernet connection) or through the serial connection. If you are accessing the IOLAN through the network, the IOLAN must already have a known IP address configured; see Using a Direct Serial Connection to Specify an IP Address getting started for information on configuring an IP address.

Through the NetworkTo connect to the IOLAN through the network to configure/manage it using the CLI, do the following:1. Start a Telnet session to the IOLAN’s IP address; for example:

telnet 10.10.201.100

2. You will get a Login: prompt. You can login as the admin user or as a user with Admin Level rights. If the login is successful, you will get a prompt that displays the IOLAN model and number of ports:Login: adminPassword:

DS1#

You will see a prompt that displays the model and number of the IOLAN. You are now ready to start configuring/managing your IOLAN using the CLI.

After you have established a connection to the IOLAN, you will get a Login: prompt. You can login as the admin user or as a user with Admin Level rights. If the login is successful, you will get a prompt that displays the IOLAN model and number of ports:Login: adminPassword:

DS1#

You will see a prompt that displays the model and number of the IOLAN. You are now ready to start configuring/managing your IOLAN using the CLI

Using the CLIAfter you have successfully logged in, you can start configuring/managing the IOLAN by typing in commands at the prompt. If you are not sure what commands are available, you can type a ? (question mark) at any time during a command to see your options.See the Command Line Interface Reference Guide for more information about the CLI.

MenuOverview

The Menu is a graphical representation of the CLI. You can look up Menu parameter explanations in the Command Line Interface Reference Guide. The only operations that the Menu does not support are the downloading and uploading of files to/from the IOLAN.

Access PlatformsThe Menu is accessed by any application that supports a Telnet session to the IOLAN’s IP address, such as Putty, SecureCRT, or from a command prompt. You can also access the Menu from a dumb terminal or PC connected to a serial port.

FeaturesThe Menu supports the following features:

You can access the IOLAN from any application that supports Telnet.You can access the IOLAN using a terminal emulator and a serial connection.

Connecting to the IOLAN Using the MenuTo connect the IOLAN using the Menu, follow the directions for Connecting to the IOLAN Using the CLI .

DHCP/BOOTP

DHCP/BOOTPOverview

Several IOLAN parameters can be configured through a DHCP/BOOTP server during the IOLAN bootup. This is particularly useful for configuring multiple IOLANs. Not all configuration parameters are supported in the DHCP/BOOTP configuration (see DHCP/BOOTP Parameters for supported configuration parameters), so you will need to use another configuration method, such as DeviceManager, WebManager or CLI, to complete the configuration.

FeaturesDHCP/BOOTP supports the following features:

DHCP/BOOTP can supply the IOLAN’s IP address. The DHCP/BOOTP server can configure certain server and user configuration parameters when the IOLAN is booted.The DHCP/BOOTP server can auto-configure the IOLAN with basic setup information (IP address, subnet/prefix bits, etc.).The DHCP/BOOTP server can download a new version of firmware when the IOLAN is rebooted.The DHCP/BOOTP server can download a full configuration file when the IOLAN is rebooted.

Connecting to the IOLAN Using DHCP/BOOTPThe IOLAN will automatically request an IP address from the DCHP/BOOTP server when the Obtain IP address automatically using DHCP/BOOTP parameter is enabled. To enable the Obtain IP address automatically using DHCP/BOOTP parameter, follow the directions in Using a Direct Serial Connection to Enable BOOTP/DHCP .

Using DHCP/BOOTPTo use DHCP/BOOTP, edit the bootp file with IOLAN configuration parameters. You can use DHCP/BOOTP to perform the following actions on a single or multiple IOLANs on bootup:

auto-configure with minimal information; for example, only an IP addressauto-configure with basic setup information (IP address, subnet/prefix bits, etc.)download a new version of firmwaredownload a full configuration file

DHCP/BOOTP is particularly useful for multiple installations: you can do all the IOLANs’ configuration in one DHCP/BOOTP file, rather than configure each IOLAN manually. Another advantage of DHCP/BOOTP is that you can connect the IOLAN to the network, turn on its power and let autoconfiguration take place. All the configuration is carried out for you during the DHCP/BOOTP process.


DHCP/BOOTP

DHCP/BOOTP ParametersThe following parameters can be set in the DHCP/BOOTP bootp file:

SW_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name of the firmware update.CONFIG_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name of the configuration file. Note: these parameters include clear text user passwords.GUI_ACCESS—Access to the IOLAN from the HTTP WebManager. Values are on or off.SECURITY—Restricts IOLAN access to devices listed in the IOLAN’s host table. Values are yes or no.TFTP_RETRY—The number of TFTP attempts before aborting. This is a numeric value, for example, 5.TFTP_TMOUT—The time, in seconds, before retrying a TFTP download/upload. This is a numeric value, for example, 3. CUSTOM_LANG—The full path, pre-fixed by a hostname/IP address (IPv4 or IPv6), and file name of a translated language file. For example, 192.101.34.211 /accounting/Iolan_ds_german.txt.

EXTRA_TERM1—(EXTRA_TERM2, EXTRA_TERM3) The full path, pre-fixed by a hostname/IP address (IPv4 or IPv6), and file name of a termcap file for a specific terminal type.


SNMP

SNMPOverview

The IOLAN supports configuration and management through SNMP. SNMP Management tools (SNMP client/MIB browser software) can be used to set IOLAN configuration parameters and/or view IOLAN statistics.Before you can configure/manage the IOLAN using SNMP, although you need to set the IOLAN IP address and configure a read-write user for SNMP version 3 or a community for SNMP version 1 or 2. You can use DeviceManager, CLI, or the Menu to set the IP address and user/community (don’t forget to reboot the IOLAN before connecting with the SNMP manager to make your changes take effect).

Access PlatformsYou can access the IOLAN SNMP MIB from any system that runs your SNMP client/MIB browser software.

FeaturesSNMP supports the following features:

You can configure SNMP traps.Since not all versions of SNMP support secure communication, password parameters must be set using another configuration method.

Connecting to the IOLAN Using SNMPBefore you can connect to the IOLAN through an SNMP Management tool or MIB browser, you need to set the following components through another configuration method.1. Configure a known IP address on the IOLAN.2. Configure a read-write user for SNMP version 3 or a community for SNMP version 1 or 2 on the

IOLAN.3. Reboot the IOLAN to make sure the changes take effect.To connect to the IOLAN through an SNMP Management tool or MIB browser, do the following:1. Load the perle-ds.MIB file from the IOLAN CD-ROM or Perle website into your SNMP

manager (this MIB works for all DS1 and TS2 models).

2. Verify that the read-write user for SNMP version 3 or a community for SNMP version 1 or 2 match the configuration on the IOLAN.

3. Type in the IOLAN’s IP address and connect to the IOLAN.You are now ready to start configuring the IOLAN using SNMP.

Note: You need to have the following MIBs installed in your SNMP manager (these are usually part of the standard SNMP client/MIB browser):

SNMPv2-SMISNMPv2-TCIPV6-TC


SNMP

Using the SNMP MIBAfter you have successfully connected to the IOLAN through your SNMP Management tool or MIB browser, expand the PERLE-IOLAN-DS-MIB folder to see the IOLAN’s parameter folders. Below is an example of the configurable parameters under the ServicesInfo folder.

The first variable in each folder is the Status variable, for example, serviceStatus. When you perform a GET on this variable, one of the following values will be returned:

1—Indicates that the container folder is active with no changes.2—Indicates that the container folder is active with change(s).

Once you have completed setting the variables in a folder, you will want to submit your changes to the IOLAN. To do this, set the Status variable to 4. If you want to discard the changes, set the Status variable to 6.

4—Indicates that the changes in the container folder are to be submitted to the IOLAN.6—Indicates that the changes in the container folder are to be discarded.

If you want to save all the changes that have been submitted to the IOLAN, you need to expand the adminInfo container folder and SET the adminFunction to 1 to write to FLASH. To make the configuration changes take effect, SET the adminFunction to 3 to reboot the IOLAN.

There are several different configuration methods available to configure the IOLAN Configuration Methods Overview for more information. This chapter describes the three main minimal configuration requirements for the IOLAN through either Easy Config Wizard (cannot configure users using this method), DeviceManager, or WebManager:1. Setting up the network—This minimally consists of configuring an IP address or enabling

DHCP/BOOTP. Once the IOLAN has an IP address, you can use any configuration method.2. Setting up the serial ports—You will want to select the serial port profile that matches the serial

port requirement/scenario for your serial device. 3. Setting up users—This is an optional step, which is only required when your implementation

requires users to access the IOLAN.

Easy Configuration WizardThe Easy Config Wizard quickly sets up the IOLAN’s network configuration and all serial ports to one of the following:

Console Management—Allows users on the network to connect to a serial device that is connected to a serial port on the IOLAN.


Setting Up the Network

TruePort (Virtual COM Port)—Allows a networked system to communicate with your serial device through a virtual COM or TTY port, using the Perle TruePort software. TCP Sockets (Raw TCP)—Allows hosts on the network to communicate with a serial device that requires raw data throughput (such as a printer or card reader) connected to the IOLAN serial port.Terminal—Allows a terminal device to connect to a specified host on the network through a serial port on the IOLAN.Printer—(SDS/STS/SCS only) Allows hosts on the network to talk to a printer using LPD or RCP connected to the IOLAN.Serial Tunneling—Allows IOLANs on the network to establish a virtual link between their serial ports. Typically, one IOLAN’s serial port is configured as a Tunnel Server and the other IOLAN’s serial port is configured as a Tunnel Client.

Setting Up the NetworkThe most important part of setting up the network is assigning an IP address to the IOLAN, whether this is a static IP address or enabling a DHCP/BOOTP-assigned IP address. You should also assign a name to the IOLAN, to make it easier to recognize. This section deals primarily with setting the IP address.

Using DeviceManagerTo use the DeviceManager, you must first install it on a Windows® operating system. The DeviceManager is able to automatically discover all IOLANs on your local network, even if they have not yet been assigned an IP address. If routers on the network have been setup to propagate multicasts, DeviceManager will also be able to discover IOLANs in other networks. The DeviceManager installation wizard can be found on the CD-ROM included in the IOLAN package.1. Connect the IOLAN to the network.2. Power on the IOLAN.3. From the CD-ROM that was included in the IOLAN packaging, select the DeviceManager link.4. Click on the link under Location and click Open to automatically start the DeviceManager

installation.5. Install the DeviceManager by following the installation wizard. On the last window, check the

Yes, I want to launch DeviceManager now. box and click the Finish button. 6. When you launch the DeviceManager, it will automatically scan the local network and display

any IOLANs that it can find.7. Any IOLAN that does not have an IP address will be displayed as Not Configured, with the

Model and MAC Address to identify the IOLAN. Highlight the IOLAN that you want to assign an IP address to and click the Assign IP button.

8. Choose the method you want to use to assign an IP address to the IOLAN:Type in the IP address that you want to assign to this IOLAN.Enable the Have the IOLAN automatically get a temporary IP address option. This will turn on DHCP/BOOTP, so the IOLAN will attempt to get its IP address from your DHCP/BOOTP server. If you don’t have a DHCP/BOOTP server, DeviceManager will temporarily assign an IP address in the range of 169.254.0.1-169.254.255.255 that will be used only for the duration of the DeviceManager/IOLAN communication.

Click the Assign IP button.9. You are now ready to configure the IOLAN. Double-click the IOLAN you just configured the IP

address for to open a configuration session. Type superuser (the factory default Admin user password) in the Login window and click OK.

10. Expand the Server Configuration folder and select Server. Verify the IP address configuration. You should also enter a name in the Server Name field to make the IOLAN easily identifiable.

11. To make your edits take effect, you need to download the new configuration file and then reboot the IOLAN. Download the configuration file to the IOLAN by selecting Tools, Download Configuration to Unit or click the Download All Changes button.

12. Reboot the IOLAN by selecting Tools, Reboot Server or click the Reboot IOLAN button.For more information on configuring the IOLAN using DeviceManager, see Chapter 5 Using DeviceManager and WebManager.

Using WebManagerTo use the WebManager as your configurator, you must first assign an IP address to the IOLAN. You can use the Easy Config Wizard to assign an IP address to the IOLAN or any of the other methods described in this section. Once the IP address is assigned to the IOLAN, simply type the IP address into the Address field of your web browser and press the Enter key.

Using a Direct Serial Connection to Specify an IP AddressYou can connect to the IOLAN’s serial console port using a PC with a terminal emulation package, such as HyperTerminal or a terminal.1. Connect the IOLAN to your PC or dumb terminal. Make sure the DIP switch is in Console mode

(desktop models, this sets the IOLAN serial port 1 to EIA-232). When connecting a terminal or PC directly (without modems), the EIA-232 signals need to be crossed over (‘null modem’ cable). See EIA-232 Cabling Diagrams for cabling diagrams.

2. Using a PC emulation application, such as HyperTerminal, or from a dumb terminal, set the Port settings to 9600 Baud, 8 Data bits, No Parity, 1 Stop Bits, and No Hardware Flow control to connect to the IOLAN.

3. When prompted, type admin for the User and superuser for the Password. You should now see the a prompt that displays the model type and port number; for example, DS1#.

4. You are now logged into the IOLAN and can set the IP address by typing from the command line using the Command Line Interface (CLI).Type:

set server internet <ipv4address>

Where ipv4address is the IP Address being assigned to the IOLAN.5. Type the following command:

save

6. If you are going to use another configuration method, such as WebManager or DeviceManager, unplug a desktop IOLAN. On a desktop IOLAN, change the DIP switch to Off Serial (DIP switch in the up position) and connect it to your serial device. Plug the IOLAN back in, automatically rebooting the IOLAN in the process.

7. If you want to complete the configuration using a direct connection, see Command Line Interface and/or Menu . After you complete configuring the IOLAN, unplug the IOLAN. If this is a desktop model, change the IOLAN DIP switch to Off Serial (DIP switch in the up position) and connect it to your serial device. Plug the IOLAN back in, automatically rebooting the IOLAN in the process.

Using a Direct Serial Connection to Enable BOOTP/DHCPIf you are using BOOTP, you need to add an entry in the BOOTP server for the IOLAN that associates the MAC address (found on the back of the IOLAN) and the IP address that you want to assign to the IOLAN. After you have made the MAC address/IP address association for BOOTP, use the following directions for BOOTP or DHCP.You can connect to the IOLAN using a PC with a terminal emulation package, such as HyperTerminal or a dumb terminal.1. Connect the IOLAN to your PC or dumb terminal. Make sure the DIP switch is in Console mode

(desktop models, this sets the IOLAN serial port to EIA-232). When connecting a terminal or PC directly (without modems), the EIA-232 signals need to be crossed over (‘null modem’ cable). See EIA-232 Cabling Diagrams for cabling diagrams.

2. Using a PC emulation application, such as HyperTerminal, or from a dumb terminal, set the Port settings to 9600 Baud, 8 Data bits, No Parity, 1 Stop Bits, and No Hardware Flow control to connect to the IOLAN.

3. When prompted, type admin for the User and superuser for the Password. You should now see the a prompt that displays the model type and port number; for example, DS1#.

4. You are now logged into the IOLAN and can set the IP address by typing from the command line using the Command Line Interface (CLI). Type the following command:

set server internet dhcp/bootp on

5. Type the following command:save

6. Type the following command:reboot

7. When the IOLAN reboots, it will automatically poll for an IP address from the DHCP/BOOTP server.

8. To view the DHCP/BOOTP assigned IP address, type the following command:show interface ethernet

If for some reason it cannot obtain an IP address from your DHCP/BOOTP server, you will have to either reconnect to the IOLAN on the console port and reboot it or push the Reset to Factory button to access the IOLAN.You are now ready to configure the IOLAN. See Configuration Methods Overview for information on the different IOLAN configuration methods.

Getting Started 49


Using ARP-PingYou can use the ARP-Ping (Address Resolution Protocol) method to temporarily assign an IP address and connect to your IOLAN to assign a permanent IP address. To use ARP-Ping to temporarily assign an IP address:1. From a local UNIX/Linux host, type the following at the system command shell prompt:

arp -s a.b.c.d aa:bb:cc:dd:ee:ff

On a Windows® 2000 or newer system, type the following at the command prompt:arp -s a.b.c.d aa-bb-cc-dd-ee-ff

(where a.b.c.d is the IPv4 address you want to temporarily assign to the IOLAN, and aa:bb:cc:dd:ee:ff is the Ethernet (MAC) address of IOLAN (found on the back of the unit).

2. Whether you use UNIX or Windows®, you are now ready to ping to the IOLAN. Here is a UNIX example of the sequence to use:arp -s 192.168.209.8 00:80:d4:00:33:4eping 192.168.209.8

From the ping command issued in step 2, the IOLAN will pickup and use the IP address entered into the ARP table in step 1. You are now ready to configure the IOLAN. See Configuration Methods Overview for information on the different IOLAN configuration methods.

For an IPv6 NetworkThe IOLAN has a factory default link local IPv6 address that takes the following format:IOLAN MAC Address: 00-80-D4-AB-CD-EFLink Local Address: fe80::0280:D4ff:feAB:CDEFThe IOLAN will also listen for IPv6 router advertisements to learn a global address. You do not need to configure an IPv4 address for IOLANs residing in an IPv6 network.You are now ready to configure the IOLAN. See Configuration Methods Overview for information on the different IOLAN configuration methods.

Setting Up the Serial Port(s)

Setting Up the Serial Port(s)The DeviceManager and WebManager have the following serial port profiles that will simplify serial port setup:

Console Management—The Console Management profile configures a serial port to provide network access to a console or administrative port. This profile sets up a serial port to support a TCP socket that listens for a Telnet connection from the network. TruePort—The TruePort profile configures a serial port to connect network servers or workstations running the TruePort software to a serial device as a virtual COM port. This profile is ideal for connecting multiple serial ports to a network system or server. TCP Sockets—The TCP Sockets profile configures a serial port to allow a serial device to communicate over a TCP network. The TCP connection can be configured to be initiated from the network, a serial device connected to the serial port, or both. This is sometimes referred to as a raw connection or a TCP raw connection.UDP Sockets—The UDP Sockets profile configures a serial port to allow communication between the network and serial devices connected to the IOLAN using the UDP protocol.Terminal—The Terminal profile configures a serial port to allow network access from a terminal connected to the IOLAN’s serial port. This profile is used to access predefined hosts on the network from the terminal.Serial Tunneling—The Serial Tunneling profile configures a serial port to establish a virtual link over the network to a serial port on another IOLAN. Both IOLAN serial ports must be configured for Serial Tunneling (typically one serial port is configured as a Tunnel Server and the other serial port as a Tunnel Client). Virtual Modem—The Virtual Modem (Vmodem) profile configures a serial port to simulate a modem. When the serial device connected to the IOLAN initiates a modem connection, the IOLAN starts up a TCP connection to another IOLAN configured with a Virtual Modem serial port or to a host running a TCP application.

Getting Started 51

Setting Up the Serial Port(s)

Control Signal I/O—The Control Signal I/O profile enables the use of the EIA-232 serial port signal pins to be used as assigned Digital Inputs or Digital Outputs.Modbus Gateway—The Modbus Gateway profile configures a serial port to act as a Modbus Master Gateway or a Modbus Slave Gateway.Custom Application/Plugin—The Custom Application/Plugin profile configures a serial port to run a custom application or IOLAN plugin. After you download the custom application files and specify the application name and any parameters you want to pass to it, the IOLAN will execute the application when the serial port is started.

Each serial port profile contains all the parameters that are required to completely configure the serial port scenario represented by the profile.To select a serial port profile in the DeviceManager, connect through the DeviceManager to the IOLAN you are configuring and select Serial, Serial Ports in the navigation pane. Highlight the serial port you want to configure and then click Edit.

When the default serial port profile Terminal displays, click the Change Profile button and select the appropriate profile for the serial port. See Chapter 6, Configuring Serial Ports for more information on the serial port profiles and their configuration parameters.

Getting Started 52

Setting Up Users

Setting Up UsersWhen you have a user who is accessing a device connected to a serial port from the network or who is accessing the network from a device connected to a serial port through the IOLAN, you can create a user account and configure the user’s access privileges. Notice that there is a Default user; the Default user’s parameters are inherited by users accessing a serial port configured for the Terminal profile with the Connect to remote system option enabled. To add a user account, click on the Users page in the navigation pane.

Click the Add button to create a user account.

To quickly add a user, fill out the field in the General tab and click OK.See Chapter 8, Configuring Users for more information about the other user parameters you can configure.

Getting Started 53

Using DeviceManager and WebManager Chapter 55

IntroductionThe DeviceManager and WebManager IOLAN managers have been designed to be very similar to use. DeviceManager is a Windows®-based application and WebManager is a browser-based application. Both options use the IOLAN’s IP address to access the IOLAN; the DeviceManager can be used to assign an IP address to a new IOLAN and the WebManager requires that the IOLAN already have an IP address before it can be used to configure the IOLAN.When using WebManager, you are required to click the Apply button each time you make a change to a configuration window/tab. In DeviceManager, you must download your configuration changes to the IOLAN either periodically or after you are done with the configuration changes. From both managers you must reboot the IOLAN in order for you configuration changes to take effect.


Navigating DeviceManager/WebManager

Navigating DeviceManager/WebManagerThe DeviceManager and WebManager have very similar navigation methods. The left-hand side of the manager is the navigation tree and the center is the configuration area. The DeviceManager has menu and quick access buttons, whereas the WebManager has system information and some navigation options on the far right-hand side.

DeviceManagerThe DeviceManager has a navigation tree that you can use to access the available Configuration and Statistics pages in the display area. When you select an option in the navigation tree, you can often navigate the tabs or buttons in the display area to access the various configuration and statistics options. See Using DeviceManager for more information on how to navigate the pages of DeviceManager.

Using DeviceManager to Connect to the IOLAN

Using DeviceManager to Connect to the IOLANDeviceManager can connect to existing IOLANs or assign an IP address to a new IOLAN. Whenever you connect to the IOLAN through the DeviceManager, you connect as the Admin user and must supply the password for the Admin user.

Starting a New SessionTo start a new session and connect to the IOLAN using the DeviceManager:1. Start the DeviceManager by selecting Start, All Programs, Perle, DeviceManager,

DeviceManager.2. When the DeviceManager starts, it searches the network for IOLANs.

If your IOLAN is not in the local network and you do not have a multicast enabled router in your network and therefore is not displayed in the selectable list, but can be pinged from your PC, you can add it to the selectable list by clicking the Add button.

Click the Add button and type in the IOLAN’s IP address; this field supports IPv4 and IPv6 addresses. Click the Close button when you have completed adding all the manual entries. Select the manually added server to connect to it.

Note: If you are not seeing IPv6 addresses in the list (you must expand the entry), see IPv6 Issues to find out how to install IPv6 support.



Assigning a Temporary IP Address to a New IOLANYou can temporarily assign an IP address to the IOLAN that is connected to your local network segment, for the purpose of connecting to it and downloading a configuration file (containing a permanent IP address). To temporarily assign an IP address to the IOLAN, do the following:1. Click the Refresh button. The IOLAN will be displayed in the IP Address column as Not

Configured.2. Select the new IOLAN and click the Assign IP button. The following window is displayed:

3. Type a valid temporary IP address into the address field or, in version 3.2 or higher, enable the Have the IOLAN automatically get a temporary IP address. If you enable the temporary IP address, the IOLAN will enable DHCP/BOOTP on your IOLAN and attempt to get an IP address from the DHCP/BOOTP server (this will permanently enable DHCP/BOOTP in your IOLAN’s configuration, until you change it). If your network does not have a DHCP/BOOTP server, the IOLAN will temporarily assign an IP address in the range of 169.254.0.1-169.254.255.255 (this IP address is only assigned for the duration of the DeviceManager/IOLAN connection).

4. Click the Assign IP button.5. Double-click the IOLAN in the IOLAN List. If this is the first time you are accessing the

IOLAN, type in the factory default Admin password, superuser, and click OK. The DeviceManager will display a window indicating that it is trying to authenticate and connect you on the IOLAN.

6. If the authentication and connection are successful, the Server Info window is displayed. You are now ready to configure the IOLAN. If authentication was unsuccessful, try to connect to the IOLAN again; you probably mistyped the password for the Admin user.

For more information about managing the IOLAN, see Configuration Files .

Version 3.2 or higherVersion 3.1 or lower



Adding/Deleting IOLANs ManuallyTo permanently add/delete IOLANs to/from the IOLAN List, click the Add button. The following window is displayed:

To permanently add the IOLAN to the IOLAN list, type in the IP address of the IOLAN and click the Add button and enter the IPv4 or IPv6 address. To permanently delete the IOLAN from the IOLAN list, select the IOLAN’s IP address and click the Delete button.

Logging in to the IOLANTo log in to the IOLAN, double-click on the IOLAN in the Device Server List. You will be prompted for the Admin Password (the default is superuser).

If the authentication and connection are successful, the IOLAN’s Server Info window is displayed.If you cannot connect to the IOLAN, you can highlight the IOLAN and click the Ping button to verify that the DeviceManager can communicate with the IOLAN’s IP Address. If the ping times out, then you might need to set up a Gateway in your IOLAN or verify that your network is communicating correctly.


Using WebManager to Connect to the IOLAN

Using WebManager to Connect to the IOLANWebManager can only connect to IOLANs that already have an assigned IP address. To connect to the IOLAN, type the IP address of the IOLAN into the Address field as such: http://10.10.234.34.You will see the login screen.

Logging into the IOLANType in the admin password in the Password field and click the Login button.

Configuration FilesCreating a New IOLAN Configuration in DeviceManager

In DeviceManager, when you select File, New, the New Configuration window is displayed.

Select the IOLAN model for which you want to create a new configuration file. Any configuration file created in this manner can only be save locally. To download a created configuration file, you must first connect to the IOLAN, import the created configuration file into DeviceManager (this is not available in WebManager), and then download the configuration file to the IOLAN and reboot it.


Managing the IOLAN

Opening an Existing Configuration FileIf you select the File, Open, a browse window is opened so you can select the configuration file you want to edit. IOLAN configuration files saved in the DeviceManager can be in the IOLAN-native binary format (.dme) or as a text file (.txt), which can be edited with a text editor. Either configuration version can be imported into the DeviceManager. IOLAN configuration files saved from WebManager can also be opened into DeviceManager.

Importing an Existing Configuration FileIf you have a local, saved configuration file that you want to download to the IOLAN, you must first connect to the IOLAN that you want to download the configuration file to. Once you have successfully logged into the IOLAN, in DeviceManager select Tools, Import Configuration from a File and in WebManager select Administration, Restore/Backup. You need to download the file in DeviceManager and in both managers you need to reboot the IOLAN.

Managing the IOLANMost of the management tasks, such as setting the time/date, downloading keys/certificates, downloading firmware, downloading custom files, resetting serial ports, etc., are found under the Tools menu option in the DeviceManager and under Administration in WebManager.


Configuring Serial Ports Chapter 66
Introduction
The Serial section is used to configure the serial ports on your IOLAN. The following configuration windows are available:

Serial Ports—This window sets up the type of connection that the serial port is being used for. This is accomplished by selecting a connection profile and then configuring the applicable parameters for that profile. See Serial Ports for more information.Advanced—This window configures those parameters that are applicable to specific environments. You will find modem and TruePort configuration options, in addition to others, here.

See Advanced for more information.

Serial PortsOverview

Each IOLAN serial port can be connected to serial device. Each serial port can then be configured according to a serial port profile that coincides with the serial device attached to that serial port and how the serial device is accessed/used.

FunctionalityWhen you select the Serial Ports navigation option, you will see a list with the number of serial ports on your IOLAN. As you configure the serial ports, the information for each serial port is displayed.

To configure/change a serial port, click the Edit button.

Serial Port Profiles

Serial Port ProfilesCommon Tabs

OverviewThere are several functions that are common to more than one profile. These functions are:

Hardware—Configure the physical serial line parameters. See Hardware Tab Field Descriptions .Packet Forwarding—Configure data packet parameters. See Packet Forwarding Tab Field Descriptions .

Hardware Tab Field DescriptionsThe Hardware tab configures all the serial port hardware connection information.

Configure the following parameters:

Serial Interface Specifies the type of serial line that is being used with the IOLAN.Data Options: EIA-232, EIA-422, or EIA-485. TS2 models support only EIA-232.Default: EIA-232

Speed Specifies the baud rate of the serial line; keep in mind that speed is affected by the length of the cable. You can also specify a custom baud rate. When you enter a custom baud rate, the IOLAN will calculate the closest baud rate available to the hardware. The exact baud rate calculated can be viewed in the Serial Ports statistics.Range: 50-230400, custom supports 50-1843200Default: 9600

Data Bits Specifies the number of bits in a transmitted character.Default: 8

65


Parity Specifies the type of parity being used for the data communication on the serial port. If you want to force a parity type, you can specify Mark for 1or Space for 0. Data Options: Even, Odd, Mark, Space, None Default: None

Stop Bits Specifies the number of stop bits that follow a byte. Data Options: 1,1.5, 2Default: 1

Duplex Used with a EIA-485 serial interface, specify whether the serial port is Full Duplex (communication both ways at the same time) or Half Duplex (communication in one direction at a time).Default: Full

TX Driver Control Used with a EIA-485 serial interface, if your application supports RTS (Request To Send), select this option. Otherwise, select Auto. Default: Auto

Flow Control Defines whether the data flow is handled by the software (Soft), hardware (Hard), Both, or None. Data Options: Soft, Hard, Both, NoneDefault: None

EnableToggle RTS Configure the Toggle RTS Feature if your application needs for RTS to be raised during character transmission.Initial Delay: configure the time in (ms) between the time the RTS signal is raised and the start of character transmission. This delay only applies if this port is not running hardware flow conrol. If hardware flow control is used, the transmission will occur as soon as CTS is raised by the modem.Final Delay: configure the time (in ms) between the time of character transmission and when RTS is dropped.Initial delay range: 1-1000 msFinal delay range: 1-1000 msDefault: Off

Enable Inbound Flow Control

Determines if input flow control is to be used.Default: Enabled

Enable Outbound Flow Control

Determines if output flow control is to be used.Default: Enabled

Monitor DSR Specifies whether the EIA-232 signal DSR (Data Set Ready) should be monitored. This is used with modems or any device that sends a DSR signal. When it is monitored and the IOLAN detects a DSR signal, the line profile is started. If both Monitor DCD and Monitor DSR are enabled, both signals must be detected before the line profile is started.Default: Disabled

Monitor DCD Specifies whether the EIA-232 signal DCD (Data Carrier Detect) should be monitored. This is used with modems or any other device that sends a DCD signal. When it is monitored and the IOLAN detects a DCD signal, the line profile is started. If both Monitor DCD and Monitor DSR are enabled, both signals must be detected before the line profile is started.Default: Disabled

66


Enable Echo Suppression

This parameter applies only to EIA-485 Half Duplex mode. All characters will be echoed to the user and transmitted across the serial ports. Some EIA-485 applications require local echo to be enabled in order to monitor the loopback data to determine that line contention has occurred. If your application cannot handle loopback data, echo suppression should be enabled. Default: Disabled

Discard Characters Received with Line Errors

When enabled, the IOLAN will discard received characters with parity or framing errors.Default: Disabled

67


Packet Forwarding Tab Field DescriptionsThe Packet Forwarding tab can be used to control/define how and when data packets are sent from the IOLAN.


Minimize Latency This option ensures that all application data is immediately forwarded to the serial device and that every character received from the device is immediately sent on the network. Select this option for timing-sensitive applications.Default: Enabled

Optimize Network Throughput

This option provides optimal network usage while ensuring that the application performance is not compromised. Select this option when you want to minimize overall packet count, such as when the connection is over a WAN.Default: Disabled

Prevent Message Fragmentation

This option detects the message, packet, or data blocking characteristics of the serial data and preserves it throughout the communication. Select this option for message-based applications or serial devices that are sensitive to inter-character delays within these messages.Default: Disabled

Delay Between Messages

The minimum time, in milliseconds, between messages that must pass before the data is forwarded by the IOLAN.Range: 0-65535Default: 250 ms

Custom Packet Forwarding

This option allows you to define the packet forwarding rules based on the packet definition or the frame definition.Default: Disabled

68


Packet Definition When enabled, this group of parameters allows you to set a variety of packet definition options. The first criteria that is met causes the packet to be transmitted. For example, if you set a Force Transmit Timer of 1000 ms and a Packet Size of 100 bytes, whichever criteria is met first is what will cause the packet to be transmitted.Default: Enabled

Packet Size The number of bytes that must be received from the serial port before the packet is transmitted to the network. A value of zero (0) ignores this parameter. Range: 0-1024 bytesDefault: 0

Idle Time The amount of time, in milliseconds, that must elapse between characters before the packet is transmitted to the network. A value of zero (0) ignores this parameter. Range: 0-65535 msDefault: 0

Enable Trigger1 Character

When enabled, specifies the character that when received will define when the packet is ready for transmission. The actual transmission of the packet is based on the Trigger Forwarding Rule. Range: Hex 0-FF Default: 0

Enable Trigger2 Character

When enabled, creates a sequence of characters that must be received to specify when the packet is ready for transmission (if the End Trigger1 character is not immediately followed by the End Trigger2 character, the IOLAN waits for another End Trigger1 character to start the End Trigger1/End Trigger2 character sequence). The actual transmission of the packet is based on the Trigger Forwarding Rule. Range: Hex 0-FF Default: 0

Frame Definition When enabled, this group of parameters allows you to control the frame that is transmitted by defining the start and end of frame character(s). If the internal buffer (1024 bytes) is full before the EOF character(s) are received, the packet will be transmitted and the EOF character(s) search will continue. Default: Disabled

SOF1 Character When enabled, the Start of Frame character defines the first character of the frame, any character(s) received before the Start of Frame character is ignored. Range: Hex 0-FF Default: 0

SOF2 Character When enabled, creates a sequence of characters that must be received to create the start of the frame (if the SOF1 character is not immediately followed by the SOF2 character, the IOLAN waits for another SOF1 character to start the SOF1/SOF2 character sequence). Range: Hex 0-FF Default: 0

Transmit SOF Character(s)

When enabled, the SOF1 or SOF1/SOF2 characters will be transmitted with the frame. If not enabled, the SOF1 or SOF1/SOF2 characters will be stripped from the transmission. Default: Disabled

69


Console Management Profile

OverviewThe Console Management profile provides access through the network to a console or administrative port of a server or router attached to the IOLAN’s serial port. This profile configures the IOLAN’s serial port to set up a TCP socket that will listen for a Telnet connection from the network.

FunctionalityUse the Console Management profile when you are configuring users who need to access a serial console port from the network.

EOF1 Character Specifies the End of Frame character, which defines when the frame is ready to be transmitted. The actual transmission of the frame is based on the Trigger Forwarding Rule. Range: Hex 0-FF Default: 0

EOF2 Character When enabled, creates a sequence of characters that must be received to define the end of the frame (if the EOF1 character is not immediately followed by the EOF2 character, the IOLAN waits for another EOF1 character to start the EOF1/EOF2 character sequence), which defines when the frame is ready to be transmitted. The actual transmission of the frame is based on the Trigger Forwarding Rule.Range: Hex 0-FF Default: 0

General Tab Field DescriptionsThe Console Management General tab configures how the serial port will be accessed by the user through the network.


Protocol Specify the connection method that users will use to communicate with a serial device connected to the IOLAN through the network.Default: Telnet

Listen for Connections on TCP Port

The port number that the IOLAN will listen on for incoming TCP connections.Default: 10001, depending on the serial port number

Enable IP Aliasing Enables/disables the ability to access a serial device connected to the serial port by an IP address (or host name that can be resolved to the Internet IP Address in a DNS network) The IOLAN can also be accessed by an IP address and port number.Default: Disabled

IP Address Users can access serial devices connected to the IOLAN through the network by the specified Internet Address (or host name that can be resolved to the Internet Address in a DNS network).Data Options: IPv4 Address

71


Advanced Tab Field DescriptionsThe Console Management Advanced tab configures serial port options that may be required by certain applications.


Authenticate User Enables/disables login/password authentication for users connecting from the network.Default: Disabled

Enable TCP Keepalive

Enables a per-connection TCP keepalive feature. After the configured number of seconds, the connection will send a gratuitous ACK to the network peer, thus either ensuring the connection stays active OR causing a dropped connection condition to be recognized.This parameter needs to be used in conjunction with Monitor Connection Status Interval parameter found in the Serial, Advanced, Advanced Settings tab. The interval determines how long the IOLAN will wait during inactivity before "testing" the connection. It should be noted that if a network connection is accidentally dropped, it can take as long as the specified interval before anyone can reconnect to the serial port.Default: Disabled

Enable Message of the Day (MOTD)

Enables/disables the display of the message of the day.Default: Disabled

Idle Timeout Use this timer to close a connection because of inactivity. When the Idle Timeout expires, the IOLAN will end the connection. Default: 0 seconds so the port will never timeoutRange: 0-4294967 seconds (about 49 days)

72


Session Timeout Use this timer to forcibly close the session/connection when the Session Timeout expires. Default: 0 seconds so the port will never timeoutRange: 0-4294967 seconds (about 49 days)

Break Handling Specifies how a break is interpreted.Data Range:

None—The IOLAN ignores the break key completely and it is not passed through to the host. Local—The IOLAN deals with the break locally. If the user is in a session, the break key has the same effect as a hot key.Remote—When the break key is pressed, the IOLAN translates this into a telnet break signal which it sends to the host machine.Break Interrupt—On some systems such as SunOS, XENIX, and AIX, a break received from the peripheral is not passed to the client properly. If the client wishes to make the break act like an interrupt key (for example, when the stty options -ignbrk and brkintr are set).

Default: None

Session Strings Controls the sending of ASCII strings to serial devices at session start and session termination as follows;

Send at Start—If configured, this string will be sent to the serial device on power-up of the IOLAN or when a kill line command is issued on this serial port. If the "monitor DSR" or "monitor DCD" options are set the string will also be sent when the monitored signal is raised.Range: 0-127 alpha-numeric characters. Non printable ascii characters must be entered in this format <027>. The decimal numbers within the brackets must be 3 digits long (example 003 not 3).Send at End—If configured, this string will be sent to the serial device when the TCP session on the LAN is terminated. If multihost is configured, this string will only be sent to the serial device when the profile is configured as a listen mode connection and after all multihost connections are terminated.Range: 0-127 alpha-numeric characters. Non printable ascii characters must be entered in this format <027>. The decimal numbers within the brackets must be 3 digits long (example 003 not 3).Delay after Send—If configured, a delay time is sent to the device. This delay can be used to provide the serial device with time to process the string before the session is initiated.Range: 0-65535 msDefault: 10 ms

Dial In If the console port is remote and will be dialing in via modem or ISDN TA, enable this parameter.Default: Disabled

Dial Out If you want the modem to dial a number when the serial port is started, enable this parameter. Default: Disabled

73


TruePort Profile

OverviewTruePort is COM Port redirector that is supplied with the IOLAN. TruePort can be installed as a client on a Workstation or Server and supports a variety of operating systems. It, in conjunction with the IOLAN, emulates a local serial port (COM port), to the application, to provide connectivity to a remote serial device over the network. The TruePort profile operates in conjunction with the TruePort software.

FunctionalityTruePort is a COM port redirector utility for the IOLAN. It can be run in two modes (these modes will be set on the client software when it is configured):

TruePort Full mode—This mode allows complete device control and operates as if the device was directly connected to the Workstation/Server’s local serial port. It provides a complete COM port interface between the attached serial device and the network. All serial controls, baud rate control, etc., are sent to the IOLAN and replicated on its associated serial port.TruePort Lite mode—This mode provides a simple raw data interface between the application and the remote serial port. Although the port will still operate as a COM port, control signals are ignored. In this mode, the serial communications parameters must be configured on the IOLAN.

See the TruePort User’s Guide for more details about the TruePort client software.

General Tab Field DescriptionsThe TruePort General tab determines how the TruePort connection is initiated and then sets up the appropriate connection parameters.

Dial Timeout The number of seconds the IOLAN will wait to establish a connection to a remote modem. Range: 1-99Default: 45 seconds

Dial Retry The number of times the IOLAN will attempt to re-establish a connection with a remote modem. Range: 0-99Default: 2

Modem The name of the predefined modem that is used on this line.

Phone The phone number to use when Dial Out is enabled.

TCP Sockets Profile

OverviewThe TCP Socket profile allows for a serial device to communicate over a TCP network. The TCP connection can be initiated from a host on the network and/or a serial device. This is typically used with an application on a Workstation or Server that communicates to a device using a specific TCP socket. This is often referred to as a RAW connection.

FunctionalityThe TCP Sockets profile permits a raw connection to be established in either direction, meaning that the connection can be initiated by either the Workstation/Server or the IOLAN.

UDP Sockets Profile

OverviewThe UDP profile configures a serial port to send or receive data to/from the LAN using the UDP protocol.

FunctionalityYou can use UDP profile in the following two basic modes. The first is to send data coming from the serial device to one or more UDP listeners on the LAN. The second is to accept UDP datagrams coming from one or more UDP senders on the LAN and forward this data to the serial device. You can also configure a combination of both which will allow you to send and receive UDP data to/from the LAN.

Sample UDP Sockets configuration screen

Four individual entries are provided to allow you greater flexibility to specify how data will be forwarded to/from the serial device. All four entries support the same configuration parameters. You can configure one or more of the entries as needed. The first thing you need to configure for an entry is the “Direction” of the data flow. The following options are available;

Disabled - UDP service not enabled.LAN to Serial - This setting will allow UDP data to be received from one or more hosts on the LAN and forwarded to the serial device attached to this serial port.Serial to LAN - This setting will allow data originating from the serial device attached to this serial port to be sent to one or more hosts on the LAN using UDP datagrams.

87


Both - Allows for data to flow from the serial device to the LAN and from the LAN to the serial device.

The role of each of the configurable parameters in an entry depends on the “Direction” selected.

When the direction is "LAN to Serial" the role of the additional parameters is as follow;Start IP Address - This is the IP address of the host from which the UDP data will originate. If the data will originate from a number of hosts, this becomes the starting IP address of a range. End IP Address - If you wish to receive data only from the single host defined by "Start IP address", leave this entry as is (0.0.0.0). If you wish to accept data from a number of hosts, this address will represent the upper end of a range starting from "Start IP Address". Only data originating from this range will be forwarded to the serial port.UDP port - This is the UPD port from which the data will originate. There are three options for this parameter.

Auto Learn - The first UDP message received will be used to define which UDP port we are going to accept UDP data from. Once learned, only data from this UDP port will be accepted. The data must also originate from a host which is in the IP range defined for this entry.Any Port - Any UDP port will be accepted as long as the data originates from a host in the IP range defined for this entry.Port - Only data originating from the UDP port configured here as well as originating from a host in the IP range defined for this entry will be accepted.

When the direction is "Serial to LAN" the role of the additional parameters is as follow;Start IP Address - This is the IP address of the host to which the serial data will be sent using UDP datagrams. If the serial data is to be sent to more than one host, this becomes the starting IP address of a range.End IP Address - If you wish to send serial data to a single host, leave this entry as is (0.0.0.0). If you wish to send the serial data to a number of hosts, this address will represent the upper end of a range starting from "Start IP Address".UDP port - This is the UPD port to which the serial data will be forwarded. For a direction of "Serial to LAN", you must specify the port to be used.

When the direction is "Both" the role of the additional parameters is as follow;Start IP Address - This is the IP address of the host to which the serial data will be sent using UDP datagrams. It is also the IP address of the host from which UDP data coming from the LAN will be accepted from. If the data is to be sent to or received from more than one host, this becomes the starting IP address of a range.End IP Address - If you wish to send serial data to a single host and only receive data from the single UDP host, leave this entry as is (0.0.0.0). If the data is to be sent to or received from more than one host, this address will represent the upper end of a range starting from "Start IP Address". Only data originating from this range will be forwarded to the serial port.UDP Port - This is the UPD port to which the serial data will be forwarded as well as the UPD port from which data originating on the LAN will be accepted from. For a direction of "Both", there are two valid option for the UDP Port as follows;

Auto Learn - The first UDP message received will be used to define which port we are going to accept UDP data from. Once learned, only data from this UDP port will be accepted and serial data being forwarded to the LAN will be sent to this UDP port. Until the port is learned, data from the serial port intended to be sent to the LAN will be discarded.

88


Port - Serial data being forwarded to the LAN from the serial device will sent to this UDP port. Only data originating from the UDP port configured here (as well as originating from a host in the IP range defined for this entry) will be forwarded to the serial device.

Special values for "Start IP address"0.0.0.0 - This is the "auto learn IP address” value which is valid only in conjunction with the "LAN to Serial" setting. The first UDP packet received for this serial port will set the IP address from which we will accept future UDP packets to be forwarded to the serial port. For this setting, leave the "End IP Address" as 0.0.0.0.255.255.255.255 - This selection is only valid in conjunction with the "LAN to Serial" setting. It will accept all UDP packets received for this serial port regardless of the originating IP address. For this setting, leave the "End IP Address" as 0.0.0.0.Subnet directed broadcast - You can use the “Start IP Address” field to enter a subnet directed broadcast address. This is done by specifying the subnet address with the host portion filled with 1s. For example, if you are on the subnet 172.16.x.x with a subnet mask of 255.255.254.0 than you would specify an IP address of 172.16.1.255 (all ones for host portion). For this setting, leave the "End IP Address" as 0.0.0.0. For any “LAN to Serial” ranges you have defined for this serial port, you must ensure that IP address of this IOLAN is not included in the range. If your IP address is within the range, you will receive the data you send via the subnet directed broadcasts as data coming in from the LAN.

An example UDP configuration is described based on the following window.

The UDP configuration window, taken from the DeviceManager, is configured to:UDP Entry 1All UDP data received from hosts that have an IP address that falls within the range of 172.16.1.25 to 172.16.1.50 and source UDP Port of 33010 will be sent to the serial device. The IOLAN will not send any data received on its serial port to the host range defined by this entry.UDP Entry 2All hosts that have an IP Address that falls within the range of 172.16.1.75 to 172.16.1.80 and who listen to UDP Port 33009 will receive UDP data from the serial device. No UDP data originating from the hosts defined by this entry will be forwarded to the serial device.UDP Entry 3All hosts that have an IP address that falls within the range of 172.16.1.1 to 172.16.1.20 and listen to Port 33001 will be sent the data from the serial device in UDP format. The serial device will only receive UDP data from the hosts in that range with a source UDP Port of 33001. The IOLAN will listen for data on the port value configured in the Listen for connections on UDP port parameter. (10001 in above example)UDP Entry 4

Listen for connections on UDP port

The IOLAN will listen for UDP packets on the specified port.Default: 1000+<port-number> (for example, 10001 for serial port 1)

Direction The direction in which information is received or relayed:The direction in which information is received or relayed:

Disabled—UDP service not enabled.LAN to Serial—UDP Port can be set to Auto Learn or Port. The IOLAN will listen on port value configured in the Listen for connections on UDP port parameter for messages coming from the learned or configured port.Serial to LAN—UDP Port can be set to Port only. The IOLAN will listen on the port value configured in the Listen for connections on UDP port parameter and will send to the configured port.Both—Messages are relayed in both directions. UDP Port can be set to Auto Learn or Port. For messages coming from the LAN to the serial device, IOLAN will listen on port value configured in the Listen for connections on UDP port parameter for messages coming from the learned or configured port. For messages going from the serial device to the LAN, the IOLAN will listen on the port value configured in the Listen for connections on UDP port parameter and will send to the configured or learned (if Auto Learn is enabled, the IOLAN must receive a UDP message before it can send one, since the port must first be (’learned’) port.Default: Both for UDP 1 and Disabled for all other UDP ranges

Start IP Address The first host IP address in the range of IP addresses (for IPv4 or IPv6) that the IOLAN will listen for messages from and/or send messages to.Field Format: IPv4 or IPv6 address

Terminal Profile

OverviewThe Terminal profile allows network access from a terminal connected to the IOLAN’s serial port. This profile is used to access pre-defined hosts on the network from the terminal.

UDP Port Determines how the IOLAN’s UDP port that will send/receive UDP messages is defined:

Auto Learn—The IOLAN will only listen to the first port that it receives a UDP packet from. Applicable when Direction is set to LAN to Serial or Both.Any Port—The IOLAN will receive messages from any port sending UDP packets. Applicable when Direction is set to LAN to Serial.Port—The port that the IOLAN will use to relay messages to servers/hosts. This option works with any Direction except Disabled. The IOLAN will listen for UDP packets on the port configured by the Listen for connections on UDP port parameter.

Default: Auto Learn

Port The UDP port to use.Default: 0 (zero)


Send at Start—If configured, this string will be sent to the serial device on power-up of the IOLAN or when a kill line command is issued on the serial port. If the "monitor DSR" or "monitor DCD" options are set, the string will also be sent when the monitored signal is raised.Range: 0-127 alpha-numeric charactersRange: Hexadecimal 0-FFDelay after Send—If configured, will inset a delay after the string is sent to the device. This delay can be used to provide the serial device with time to process the string before the session is initiated or terminated.Default: 10 ms

91


FunctionalityThis profile can be setup in two ways:1. The user can be required to log into the IOLAN and then a connection to a host can be

established.2. The user connecting to the serial port will be directly connected a host.

TCP Port The TCP Port that the IOLAN will use to connect to the host.Default: 23

Automatically If the serial port hardware parameters have been setup to monitor DSR or DCD, the host session will be started once the signals are detected. If no hardware signals are being monitored, the IOLAN will initiate the session immediately after being powered up.Default: Enabled

When any data is received

Initiates a connection to the specified host when any data is received on the serial port.Default: Disabled

93




When <hex value> is received

Initiates a connection to the specified host only when the specified character is received on the serial port.Default: Disabled



Reset Terminal on disconnect

When enabled, resets the terminal definition connected to the serial port when a user logs out.Default: Disabled

Allow Port Locking When enabled, the user can lock his terminal with a password using the Hotkey Prefix (default Ctrl-a) ^a l (lowercase L). The IOLAN prompts the user for a password and a confirmation. Default: Disabled

94


Hotkey Prefix The prefix that a user types to lock a serial port or redraw the Menu. Data Range:

^a l—(Lowercase L) Locks the serial port until the user unlocks it. The user is prompted for a password (any password, excluding spaces) and locks the serial port. Next, the user must retype the password to unlock the serial port.^r—When you switch from a session back to the Menu, the screen may not be redrawn correctly. If this happens, use this command to redraw it properly. This is always Ctrl R, regardless of the Hotkey Prefix.

You can use the Hotkey Prefix key to lock a serial port only when the Allow Port Locking parameter is enabled.Default: Hex 01 (Ctrl-a, ^a)




Send at Start—If configured, this string will be sent to the serial device on power-up of the IOLAN or when a kill line command is issued on this serial port. If the "monitor DSR" or "monitor DCD" options are set, the string will also be sent when the monitored signal is raised. Range: 0-127 alpha-numeric charactersRange: Hexadecimal 0-FFDelay after Send—If configured, will inset a delay after the string is sent to the device. This delay can be used to provide the serial device with time to process the string before the session is initiated or terminated.Default: 10 ms

Serial Tunneling Profile

OverviewThe Serial Tunneling profile allows two IOLANs to be connected back-to-back over the network to establish a virtual link between two serial ports based on RFC 2217.

FunctionalityThe serial device that initiates the connection is the Tunnel Client and the destination is the Tunnel Server, although once the serial communication tunnel has been successfully established, communication can go both ways.

A more detailed implementation of the Serial Tunneling profile is as follows:

The Server Tunnel will also support Telnet Com Port Control protocol as detailed in RFC 2217.

The IOLAN serial port signals will also follow the signals on the other serial port. If one serial port receives DSR then it will raise DTR on the other serial port. If one serial port receives CTS then it will raise RTS on the other serial port. The CD signal is ignored.

Escape Defines the escape character. Returns you to the command line mode. This value is in hexadecimal.Default: 1d (ASCII value GS)

Virtual Modem Profile

OverviewVirtual Modem (Vmodem) is a feature of the IOLAN that provides a modem interface to a serial device. It will respond to AT commands and provide signals in the same way that a serially attached modem would. This feature is typically used when you are replacing dial-up modems with the IOLAN in order to provide Ethernet network connectivity.

FunctionalityThe serial port will behave in exactly the same fashion as it would if it were connected to a modem. Using AT commands, it can configure the modem and the issue a dial-out request (ATTD). The IOLAN will then translate the dial request into a TCP connection and data will be begin to flow in both directions. The connection can be terminated by ’hanging’ up the phone line.You can also manually start a connection by typing ATD<ip_address>,<port_number> and end the connection by typing +++ATH. The ip_address can be in IPv4 or IPv6 formats and is the IP address of the receiver. For example, ATD123.34.23.43,10001 or you can use ATD12303402304310001, without any punctuation (although you do need to add zeros where there are not three digits presents, so that the IP address is 12 digits long).

101




Listen on TCP Port The IOLAN TCP port that the IOLAN will listen on. Default: 10000 + serial port number (for example, serial port 12 defaults to 10012)

Host Name The preconfigured target host name.

TCP Port The port number the target host is listening on for messages.Default: 0 (zero)

Connect Manually Via AT Command

When enabled, the virtual modem requires an AT command before it establishes a connection. Specify this option when your modem application sends a phone number or other AT command to a modem. The serial device can supply an IP address directly or it can provide a phone number that will be translated into an IP address by the IOLAN using the mapping table.Default: Disabled

Phone Number to Host Mapping Button

When your modem application provides a phone number in an AT command string, you can map that phone number to the destination host.

See Phone Number to Host Mapping for information about the window that appears when you click this button.

Send Connection Status As

Control Signal I/O Profile

OverviewThe Control Signal I/O profile is only available on IOLAN I/O models. When you configure a serial port for Control Signal I/O, you are using the DSR, DCD, CTS, DTR, and RTS serial pins for I/O channel Digital Input (DSR, DCD, and CTS) or Digital Output (DTR and RTS).

FunctionalityThe Control Signal I/O profile enables the use of the EIA-232 serial port pins to be used as assigned Digital Inputs or Digital Outputs.

General Tab Field DescriptionsThe General tab displays the signal pins. This window is also used to enable/disable the signal pins.

Phone Number Specify the phone number your modem application sends to the modem. Note: The IOLAN does not validate the phone number, so it must be entered in the exact way the application will send it. For example, if you enter 555-1212 in this table and the application sends 5551212, the IOLAN will not match the two numbers. Spaces will be ignored.

Host IP Address Select the host name (from the host table) of the IOLAN that is receiving the virtual modem connection.

Configuring Users Chapter 88
Introduction
You can configure up to four users in the IOLAN’s local user database, in addition to the admin user. A user can even represent a device, like a barcode reader or a card swipe device, that you want to be authenticated.When users are connecting to the IOLAN via serial ports, the user database can be used to:

Have the user authenticated prior to establishing a connection to a network host.Establish a different connection type to the host specific to each user.Create a profile different from the Default user profile.

When users are connecting to the IOLAN from a network connection, the user database can be used to:

Authenticate users prior to providing access to a serially attached console port (such as a Unix server or router).


User Settings

User SettingsOverview

The Users window allows you to add, edit, and delete users from the IOLAN.

FunctionalityThe Users window displays the users who have been configured. You can add users, edit existing users, or delete users from this window. See Adding/Editing Users for information on the parameters available when adding or editing a user.

129

Adding/Editing Users

Adding/Editing UsersGeneral Tab

OverviewThe General tab configures the basic user information.

FunctionalityYou must, minimally, provide a User Name and Level for a user.

Field Descriptions


User Name The name of the user. Restrictions: Do not use spaces.

Password The password the user will need to enter to login to the IOLAN.

Confirm Password Enter the user’s password again to verify it is entered correctly.

130


Level The access that a user is allowed.Data Options:

Admin—The admin level user has total access to the IOLAN. You can create more than one admin user account but we recommend that you only have one. They can monitor and configure the IOLAN. Users configured with this level can access the unit either via serial Terminal Profile connection or via a network originated Telnet connection to the IOLAN.Normal—The Normal level user has limited access to the IOLAN. Limited CLI commands and Menu access are available with the ability to configure the user’s own configuration settings. Users configured with this level can access the unit either via serial Terminal Profile connection or via a network originated Telnet connection to the IOLAN.Restricted—The Restricted level user can only access predefined sessions or access the Easy Port Access menu. Users configured with this level will be restricted to pre-defined sessions or limited CLI commands when connecting through the serial port via the Terminal Profile. The CLI commands are limited to those used for initiating a session. If connection to the IOLAN is done with Telnet from the network, the user will be presented with the Easy Port Access menu.Menu—The menu level user will only be able to access predefined session when connecting through a serial port with the Terminal profile or will be limited to the Easy Port Access menu when connecting from the network. The Easy Port Access allows the user to connect to the accessible line without disconnecting their initial connection to the IOLAN. Does not have any access to CLI commands.

When the Admin user logs into the IOLAN, the prompt ends with a #, whereas all other users’ prompts ends with a $ or £, depending on the character set.Default: Normal

Note: A technique for giving a serially attach user (dial-in or terminal attached), the same menus as one that is network connected is to do the following:1. Define the serial port with a Terminal Profile using telnet protocol with a direct

connection to Host IP address 127.0.0.0 (local loop back).2. When the user connects to that serial port a Telnet session will be established to the

IOLAN and the user will appear to have connected from the network.

131


Services Tab

OverviewThe Services tab configures the connection parameters for a user. Any connection parameters configured in this window will override the serial port connection parameters.

FunctionalityWhen a Terminal profile is set for the serial port and Require Login has been selected, user’s accessing the IOLAN through the serial port will be authenticated. Once authentication is successful, the IOLAN will start a Telnet connection to the specified Host IP/TCP Port.Within the Terminal profile, there are a number of settings that apply to possible Services. Once it is known which user is connected, and which service is to be used, then the settings from both the Terminal profile and the user are used. User parameters take precedence over serial port parameters.

Field Descriptions


Service Used in conjunction with the Terminal Profile. After the user has successfully been authenticated, the specified service is started.Data Options: DSPrompt, Telnet, TCP ClearDefault: DSPrompt

Host IP When the User Service is set to Telnet or TCP Clear, the target host IP address. If no IP address is specified, the Host IP value in the Default User configuration will be used. Default: 0.0.0.0.

TCP Port When the User Service is Telnet, this is the target port number. The default value will change based on the type of Service selected; the most common known port numbers are used as the default values.

132


Advanced Tab

OverviewThe Advanced tab is used to configure those parameters that control the user session; this includes session length, language, the hotkey used for switching between sessions.

Field Descriptions


Idle Timeout The amount of time, in seconds, before the IOLAN closes a connection due to inactivity. The default value is 0 (zero), meaning that the Idle Timer will not expire (the connection is open permanently). The User Idle Timeout will override all other Serial Port Idle Timeout parameters.Range: 0-4294967Default: 0

Session Timeout The amount of time, in seconds, before the IOLAN forcibly closes a user’s session (connection). The default value is 0 (zero), meaning that the session timer will not expire (the session is open permanently, or until the user logs out). The User Session Timeout will override all other Serial Port Session Timeout parameters.Range: 0-4294967Default: 0

Language You can specify whether a user will use English or Custom Language as the language that appears in the Menu or CLI. The IOLAN supports one custom language that must be downloaded to the IOLAN.Default: English

See Language Support for more information about Custom Languages.

133


Sessions Tab

OverviewThe Sessions tab is used to configure specific connections for users who are accessing the network through the IOLAN’s serial port.

FunctionalityUsers who have successfully logged into the IOLAN (User Service set to DSprompt) can start up to four login sessions on network hosts. These users start sessions through the EasyPort Menu option Sessions.Multiple sessions can be run simultaneously to the same host or to different hosts. Users can switch between different sessions and also between sessions and the IOLAN using Hotkey commands (see Hotkey Prefix for a list of commands).Users with Admin or Normal privileges can define new sessions and use them to connect to Network hosts; they can even configure them to start automatically on login to the IOLAN. Restricted and Menu users can only start sessions predefined for them in their user configuration.

Hotkey Prefix The prefix that a user types to control the current session.Data Options:

â number—To switch from one session to another, press â (Ctrl-a) and then the required session number. For example, â 2 would switch you to session 2. Pressing â 0 will return you to the IOLAN Menu.â n—Display the next session. The current session will remain active. The lowest numbered active session will be displayed.â p—Display the previous session. The current session will remain active. The highest numbered active session will be displayed.â m—To exit a session and return to the IOLAN. You will be returned to the menu. The session will be left running.â l—(Lowercase L) Locks the serial port until the user unlocks it. The user is prompted for a password (any password, excluding spaces) and the serial port is locked. The user must retype the password to unlock the serial port.^r—When you switch from a session back to the Menu, the screen may not be redrawn correctly. If this happens, use this command to redraw it properly. This is always Ctrl R, regardless of the Hotkey Prefix.

The User Hotkey Prefix value overrides the Serial Port Hotkey Prefix value. You can use the Hotkey Prefix keys to lock a serial port only when the serial port’s Allow Port Locking parameter is enabled.Default: Hex 01 (Ctrl-a or â)

134

135


Serial Port Access Tab

OverviewThe Serial Port Access tab controls the user’s read/write access on any given IOLAN serial port. This pertains to users that are connecting from the network to a serial device over a Console Management type session.This can be useful when you have multiple users connecting to the same serial device and you wish to control the viewing and/or the write to and from the device. See User Authentication parameters in the Console Management Profile for the serial port settings.

Field Descriptions


Serial Port Access Specifies the user access rights to each IOLAN serial port device. There can be multiple users connected to a particular serial device and these settings determine the rights of this user for any of the listed serial ports.Data Options:

Read/Write—The user has read and write access to the serial port. Read In—The User will see data going to the serial port, from all network-connected users that have write privileges to this serial port.Read Out—The user will have access to all data originating from the serial device.

Users can read data going in both directions by selecting both the Read In and Read Out options.Default: Read/Write

136

Configuring Security Chapter 99
Introduction
The Security group includes the following configuration options:Services—This configuration window is used to enable/disabled client and daemon services that run in the IOLAN. See Services for more information.

ServicesOverview

Services are either daemon or client processes that run on the IOLAN. You can disable any of the services for security reasons.

FunctionalityIf you disable any of the daemons, it can affect how the IOLAN can be used or accessed. For example, if you disable the WebManager service, you will not be able to access the IOLAN with the WebManager. If you disable the DeviceManager service, the DeviceManager will not be able to connect to the IOLAN. If you do not want to allow users to Telnet to the IOLAN, you can disable the Telnet Server service; therefore, disabling daemons can also be used as an added security method for accessing the IOLAN.By default, all daemon and client applications are enabled and running on the IOLAN.


Services

Field Descriptions

Enable/disable the following options:

Telnet Server Telnet daemon process in the IOLAN listening on TCP port 23.

TruePort Full Mode

The TruePort daemon process in the IOLAN that supports TruePort Full Mode on UDP port 668. You can still communicate with the IOLAN in Light Mode when this service is disabled.

Syslog Client Syslog client process in the IOLAN.

Modbus Modbus daemon process in the IOLAN listening on port 502.

SNMP SNMP daemon process in the IOLAN listening on port 161 and sending on port 162.

DeviceManager DeviceManager daemon process in the IOLAN. If you disable this service, you will not be able to connect to the IOLAN with the DeviceManager application. The DeviceManager listens on port 33812 and sends on port 33813.

WebManager (HTTP)

WebManager daemon process in the IOLAN listening on port 80.

Note: TCP ports 2601, 2602 and 2603 are used internally by the IOLAN.

Failsafe Timer Functionality

OverviewThe Failsafe Timer tab configures the I/O failsafe timer. The Failsafe Timer is enabled on a global basis and provides a trigger mechanism that can be configured for each channel when no I/O traffic has occurred for the specified amount of time. This traffic information would include any statistical data updates based on the refresh timer for Statistics.A Failsafe Action can be configured for each Digital Output channel, each Serial Signal Output pin (DTR and RTS), and each Relay channel to either Activate or Deactivate the output.The Failsafe Timer has a different function when I/O Extension is enabled for Digital Output channels, Relay channels, or the Serial Signal Output pins (DTR and RTS). For I/O Extension, the Failsafe Timer provides a per channel or per serial signal output pin trigger mechanism that is activated when there are no TCP sessions for the specified amount of time.

OverviewThe UDP tab configures the I/O UDP broadcast settings. The I/O UDP broadcast feature periodically broadcasts the I/O channel status in a UDP message.You can configure up to four sets of IP address entries (each entry consisting of a start and end IP address range) to broadcast I/O status data. The broadcast frequency of the UDP packets to the configured UDP IP addresses can be defined to accommodate network traffic and monitoring PC application requirements. For details of the UDP I/O datagram see I/O UDP .

Field Descriptions


Enable I/O Failsafe Timer

Enables/disables the Failsafe Timer. This is the global setting that must be enabled to set the Failsafe Action on the channel for digital output and relay channels or output signal pins. When this timer expires because of no I/O activity within the specified time interval, the Failsafe Action set for the channel determines the action on the output. When the channel or serial signal pin is configured for I/O extension, the timer expires there are no TCP sessions for the specified time interval.Default: Disabled

Channels

ChannelsThe Channels section displays the I/O Channels window, through which you can enable/disable the I/O channels.

Highlight a channel and then click the Edit button to configure the parameters for that channel.

Analog

OverviewAnalog channels monitor current/voltage input. Note that the internal jumpers must match the software setting (by default, they are set to Current); see Analog Input Module to find out how to set the internal jumpers.For example, in an industrial freezer warehouse, the IOLAN A4R2 is used to monitor humidity transducers, which are in place to help prevent freezer burn. If the humidity reaches a certain percentage (monitored by an Analog channel) a syslog message is sent to the Monitoring Application. The Monitoring Application then sends a command to the IOLAN via the Perle API that causes the Relay channel to activate an internal freezer dehumidifier. The relay is turned off when the Analog channel sends a clear syslog message to the Monitoring Application and the Relay channel is deactivated.

Channels

Digital Input

OverviewWhen the channel is set for digital input, it monitors voltage or current. Note that the internal jumpers must match the software setting and must be set to Input, which is the default; see Digital I/O Module to find out how to set the internal jumpers.

FunctionalityThe Digital input channels allow you to configure the following options:

You can choose to remember the last state change, or latch, that occurred. Your options are to latch (remember) when the state changes from inactive to active or active to inactive.You can choose to invert the signal, which is useful if your sensor is wired in such a way that closed is actually inactive, whereas closed is normally considered active.You can also configure an alarm trigger and clear mode based on whether the Digital input is active or inactive, sending a syslog message and/or SNMP trap when the alarm is triggered or cleared.

In an industrial freezer warehouse example, a D4 is used to monitor the open door sensor, so that every time a freezer door is opened, an alarm is triggered and a syslog message is sent to a syslog server, where the monitoring application notes the time.

Latch Latches (remembers) the activity transition (active to inactive or inactive to active). Data Options: None, Inactive-to-Active, Active-to-InactiveDefault: None

Invert Signal When enabled, inverts the actual condition of the I/O signal in the status; therefore, an inactive status will be displayed as active.Default: Disabled

Trigger When the trigger condition is met, triggers the specified alarm action. Data Options:

Disabled—No alarm settings. This is the default.Inactive—When the expected Digital input is active, going inactive will trigger an alarm.Active—When the expected Digital input is inactive, going active will trigger an alarm.

Default: Disabled

148

Channels

Digital Output

OverviewWhen the channel is set for digital output, either voltage is applied to the channel or the channel is grounded. Note that the internal jumpers must match the software setting and must be set to Output (by default, they are set to Input); see Digital I/O Module to find out how to set the internal jumpers.

FunctionalityThe Digital output channels support three types of Digital output: sink (voltage), source (ground), and sink and source (apply voltage or ground). For the output type, you can configure the following options:

You can choose to manually activate/deactivate the Digital output.You can choose to manually activate/deactivate the Digital output and then specify that the Digital output will either pulse (you get to specify the active and inactive pulse times) continuously or for a specified number of pulse counts.You can choose to manually activate/deactivate the Digital output and then specify a delay before the output goes from inactive to active or active to inactive.You can also specify a failsafe action that can either activate or inactivate the Digital output when the failsafe timer is triggered (see Failsafe Timer Functionality for more information).

In an industrial freezer warehouse, the IOLAN D4 is used to monitor the freezer doors. When one of the industrial freezer doors are left open for more than five minutes, the Monitoring Application (using the Perle API) starts the Digital output sink, causing the strobe light on top of the offending freezer to activate.

Auto Clear Mode When enabled, automatically clears the alarm when the trigger condition changes; for example, if the Trigger is Inactive and the alarm is triggered, once the input becomes active again, the alarm will automatically be cleared Default: Enabled

Manual Clear Mode

When enabled, a triggered alarm must be manually cleared. Default: Disabled

Relay

OverviewRelay channels can open or close a contact for a higher voltage circuit using a lower level control voltage. The Relay output channels work as a physical on/off switch, and are used to drive higher voltage devices with a lower controlling voltage.You can configure the following Relay output channel options:

You can choose to manually activate/deactivate the Relay output.You can choose to manually activate/deactivate the Relay output and then specify that the Relay output will either pulse (you get to specify the active and inactive pulse times) continuously or for a specified number of pulse counts.You can choose to manually activate/deactivate the Relay output and then specify a delay before the output goes from inactive to active or active to inactive.You can also specify a failsafe action that can either active or inactivate the Relay output when the failsafe timer is triggered (see Failsafe Timer Functionality for more information).

Digital I/O Extension

OverviewThe Digital I/O extension feature connects a digital input signal to digital output(s)/relay(s) and/or a TCP/IP application over an IP network. Therefore, when the state of the digital input changes, you can also change the state of the digital output or relay channel or output serial signal pin on a local I/O channel(s), other IOLAN I/O channels, other IOLAN serial signal pins, or the data can be sent to an application(s).For example, when the door opens (I/O digital input sensor) in a factory, a light goes on in the reception office (remote IOLAN relay channel), and the door open/close is logged by an application on a remote host.

Active Signal Width

How long the channel will be active during the pulse mode. Range: 1-9999 x 100 msDefault: 1 (100 ms)

Delay When a deactivate command is issued, a delay is implemented before the command is executed. Range: 1-9999 x 100 msDefault: 1 (100 ms)

FunctionalityThe Digital I/O extension feature requires the digital input to be connected to one or more digital outputs/relays (local or on another IOLAN model), output serial signal pins, and/or TCP/IP applications. In order to create a successful connection between the input and output or application, one side must be must be set to Listen for connection and the other side must be set to Connect to. When the state of an input channel changes, a message is sent to all sessions currently associated with that channel.When the IOLAN is communicating to an application, there is no need for the output channel or application to respond to messages from the input channel. Each input channel is reported individually, so the receiving application gets the status only at the point at which the channel state has changed. The message format (from input channel to output channel/application) consists of 20 bytes per status; 10 bytes are currently used and 10 are being reserved for future use.

Message type: (1 Byte)0 = Digital input status1 = Serial I/O status

Input number: (1 Byte)Digital input will be 1, 2, 3, or 4 to represent the channel numberSerial I/O will be 5 = DSR, 6 = DCD, or 7 = CTS

MAC Address of the IOLAN sending the input information. (6 Bytes)Current Alarm State: (1 Byte)

0 = Not in alarm1 = In Alarm

Current Status of Input: (1 Byte)0 = Inactive for digital input.1 = Active for digital input.

Reserved for future use. Reserved bytes will have the value 0x00. (10 Bytes)Applications should be written in such a way so that they look at the Message type byte to determine the format of the message. If the application encounters a Message type it does not recognize, it should discard the message and read the next 20 byte block.

Channels

Field DescriptionsThe Local connection option is different depending on whether you are configuring a Digital Input or a Digital Output/Relay channel. The Local connection option for Digital Input lists all the local Digital Output channels or output serial signal pins that it is associated with. Digital Input can be connected to multiple local Digital Output or Relay channels or output serial signal pins. However, a Digital Output can only be associated with one Digital Input channel or input serial signal pin. The Local connection option for Digital Output configures the specific local Digital Input channel or input serial signal pin on the same IOLAN that it is to be connected to.

When this option is enabled, you need to define a primary host that the I/O channel will communicate to and a backup host, in the event that the I/O channel loses communication to the primary host. The I/O channel will first establish a connection to the primary host. Should the connection to the primary host be lost (or never established), the I/O channel will establish a connection the backup host. Once connected to the backup, the I/O channel will attempt to re-establish a connection to the Primary host, once this is successfully done, it gracefully shuts down the backup connection.Default: Disabled

Alarm SettingsAnalog and Temperature input models support an Alarm mechanism in which you can specify up to five severity levels of alarm triggers and clear levels; the alarm triggers/clear levels can activate in either increasing or decreasing severity levels. Each time an alarm is triggered or cleared, you can specify any combination of the following to be initiated:

An SNMP trapA message to syslog

Basic Analog Alarm SettingsThe basic Analog Alarm Settings window allows you to configure one severity alarm, whereas the advanced window allows you to configure up to five severity alarm levels.


Trigger alarm when input value is

Specify the value that will trigger an alarm, the measurement is based on the Type and Range that you specify. This value must not fall within the scope of the value used to clear an alarm.

Clear alarm when input value is

Specify that value that will clear an alarm, the measurement is based on the Type and Range that you specify. This value must not fall within the scope of the value used to trigger an alarm.

Send Syslog Alert When enabled, sends a message to syslog when an alarm is triggered or cleared. The syslog entry includes the severity level and the value that caused the alarm to trigger or clear. The syslog message is associated with Level Critical.Default: Disabled

Send SNMP Alert When enabled, sends an SNMP trap when an alarm is triggered or cleared. The trap consists of the severity level and whether the alarm was triggered or cleared.Default: Disabled

Channels

Advanced Analog Alarm SettingsThe advanced Analog Alarm Settings window expands the basic alarm settings options to up to five severity levels.


Trigger Type If the Trigger Type is Low, an alarm is triggered when the input drops below the specified Trigger value; other severity level trigger values must decrease in value with each subsequent level. If the Trigger Type is High, an alarm is triggered when the input is higher than the specified Trigger value; other severity level trigger values must increase in value with each subsequent level.

Clear Mode To clear an alarm, the input must drop below the specified value when Trigger Type is High or go above the specified value when Trigger Type is Low.

Level 1-5 Defines the Level severity settings for up to five levels. If the Trigger Type is Low, an alarm is triggered when the input drops below the specified Trigger value; other severity level trigger values must decrease in value with each subsequent level. If the Trigger Type is High, an alarm is triggered when the input is higher than the specified Trigger value; other severity level trigger values must increase in value with each subsequent level.

Trigger If the Trigger Type is Low, an alarm is triggered when the input drops below the specified Trigger value; other severity level trigger values must decrease in value with each subsequent level. If the Trigger Type is High, an alarm is triggered when the input is higher than the specified Trigger value; other severity level trigger values must increase in value with each subsequent level.

I/O UDP

I/O UDPIndustrial applications often monitor the status of I/O devices such as sensors, alarms, relays, etc. by polling for I/O data. The IOLAN’s I/O UDP feature can help to minimize network traffic by broadcasting I/O status to industrial applications on specified intervals, providing I/O status in a timely manner.The IOLAN’s I/O UDP broadcast feature sends the status of attached I/O devices to defined hosts on the network. Depending upon the IOLAN model and the configuration of the I/O channels, the UDP packet contains the current status and/or data of each enabled I/O channel or serial pin signal.

UDP Unicast FormatPC applications must be able to interpret the UDP packet to obtain I/O channel status and data. This section provides the detailed structure of the UDP datagram and its data format.

UDP Broadcast Packet

Each section, with the exceptions of the Version and Total Packet Length sections, is comprised of its own subset of bytes.

Version—The current version of the format of I/O UDP broadcast packet. Total Packet Length—The total length of the UDP packet. Analog Section—The Analog Section of the UDP packet, which contains data/status of the Analog I/O channels. The Analog Channel Data subsection (within the Analog Section) will only exist if the channel(s) is enabled.Digital/Relay Section—The Digital/Relay Section of the UDP packet, which contains status of Digital and Relay I/O channels. The Channel Data subsection within the Digital/Relay Section will always be present.Serial Pin Signal Section—The Serial Pin Signal Section of the UDP packet, which contains the status of the IOLAN’s serial port’s control signal pins. The Serial Pin Signal Data subsection within the Serial Signal Pins Section will always be present.


Version(1 Byte)

Total Packet Length(2 Bytes)

Analog Section Digital/Relay Section Serial Pin Signal Section

Note: All 2 byte values are in big Endian (network) order. All 4 byte values are IEEE 754 single precision floating point numbers in big Endian (network) order.

164

I/O UDP

Analog SectionThe Analog Section of the UDP packet is comprised of I/O data for each enabled Analog channel.

Section Length—The total length of the Analog section (this value will vary, the field length is 2 Bytes). This value will vary because it will contain one Analog Channel Data subsection (18 bytes) for each Analog channel that is enabled.Channel Enabled—The Channel Enabled field is 1 byte in least significant bit order, for each channel. If the channel is enabled, the bit is set to 1. If the channel is disabled, the bit is set to 0 (zero).

Analog Channel Data—Consists of Analog Channel Data for each enabled Analog channel on the IOLAN. If an Analog channel is disabled, there is no data for that channel. Therefore, the Analog Section will contain the Section Length value, the Channel Enabled value, and 18 bytes of I/O data for each enabled Analog channel. For example, an IOLAN I/O model with four Analog channels that has only three of those Analog channels enabled will contain 54 bytes of Analog Channel Data (18 bytes * 3 Analog channels).The following values make up the Analog Channel Data for each enabled Analog channel:

curRawValue—The current raw value received by the channel.minRawValue—The minimum raw value received by the channel until it is cleared.maxRawValue—The maximum raw value received from the channel until it is cleared.curEngValue—The current raw value that has been converted to voltage/current for Analog or Celsius/Fahrenheit for Temperature.minEngValue—The minimum raw value that has been converted to voltage/current for Analog or Celsius/Fahrenheit for Temperature until it is cleared.maxEngValue—The maximum raw value that has been converted to voltage/current for Analog or Celsius/Fahrenheit for Temperature until it is cleared.

Note: If the IOLAN I/O model does not support Analog channels, the Analog Channel Data subsection of the Analog Section will NOT be present in the UDP packet.

I/O UDP

Digital/Relay SectionThe Digital/Relay Section of the UDP packet provides the status of Digital and Relay channels. The data for the status of each channel is represented by 1 byte, with each bit representing a channel (least significant bit format).

Length—The length of Digital/Relay Section within the UDP packet (this value will always be 2 Bytes).Channel Enabled—This is based on the configuration of the Digital/Relay channels. The Channel Enabled field is 1 byte in least significant bit order, for each channel. If the channel is enabled, the bit is set to 1. If the channel is disabled, the bit is set to 0 (zero).

Digital/Relay Channel Data—Each bit represents a channel status, 1 for on or 0 for off (unless the channel has been configured to be inverted, in which case 0 is on and 1 if off).

Serial Pin Signal SectionThe Serial Pin Signal Section of the UDP packet provides the status of the serial pin signals from the IOLAN’s serial port. Each serial pin signal (DSR, DTR, CTS, etc.) is mapped to a bit in the 1-byte data section.

Length—The total length of the Serial Pin Signal Data (this value will always be 2 Bytes).Pin Enabled—This based upon the configuration of the signal pins on the serial port. When the serial port profile is set to Control I/O and a serial pin signal(s) is enabled, the bit is set to 1. For any serial pin signals that are disabled, the bit is set to 0 (zero) and any data associated with those serial pin signals should be ignored.

Serial Pin Signal Data—1 byte with each bit being set to high (1) or low (0) for the appropriate serial pin signals.

Note: The Digital/Relay Channel Data subsection is present in the UDP packet regardless of whether or not the IOLAN model supports Digital/Relay channels.

Accessing I/O Data Via TruePort

Accessing I/O Data Via TruePortIntroduction

Analog and Digital I/O data, as well as output control, can be accessed in several ways. To have access from an application running on a workstation or server, the I/O Applications Program Interface (API) provided within Trueport can be used. This API uses a command/response format to get or set data on each individual I/O channel register. A sample program (ioapiotp.c) demonstrating typical usage can be found on the IOLAN product CD-ROM.

SetupAfter TruePort has been properly installed and configured on the workstation or server and initiated from the application, it will setup a connection to the appropriate IOLAN. It will then be available to relay commands to the IOLAN and communicate responses back the application. TruePort will create a COM port to which the application can write commands to and read responses from. Since all communications are done via this COM port, the application need only use standard serial communication interface calls. The following steps should be taken:1. Install the Trueport software on the server or workstation on which the application will be

running.2. Configure the virtual communication port (COM) (see TruePort User Guide for details)3. Run the application. Typically the application will:

1. Open the COM port.2. Send Commands to the COM port using standard write commands.3. Read Responses from the COM port using standard read commands.

4. Once the desired operations are completed, the COM port can be closed.

Note: All commands are forwarded to the IOLAN over the network where the specific I/O channel registers are modified or read, and then responses are sent back to TruePort where they will be made available to be read from the COM port.

175


Format of API CommandsThere are two groups of commands:

Get Commands—Retrieve values of the I/O channel registersSet Commands—Set values on the I/O channel registers.

I/O Channel registers are all assigned unique addresses, which need to be referenced in all of the commands. Please refer to the documentation specific you the applicable mode, for the list and addresses of all the registers.

Get CommandsThe following tables show the general structure to be used for Get commands.

Command Format

Configuring the System Chapter 1111
Introduction
This chapter describes the alerts (syslog) that can be configured for the IOLAN and the advanced options (SNMP, custom applications/plugins, and other miscellaneous configuration options) that you will want to look at to see if they are required for your implementation.

AlertsSyslog

OverviewThe IOLAN can be configured to send system log messages to a syslog daemon running on a remote host if the Syslog service is activated. You can configure a primary and secondary host for the syslog information and specify the level for which you want syslog information sent.

Field Descriptions


Note: You must ensure that the Syslog Client service in the Security, Services window is enabled (by default it is enabled) for these settings to work.

Primary Host The first preconfigured host that the IOLAN will attempt to send system log messages to; messages will be displayed on the host’s monitor.Default: None


Management

ManagementSNMP

OverviewIf you are using SNMP to manage/configure the IOLAN, or to view statistics or traps, you must set up a User in SNMP version 3 or a Community in SNMP version 1,2 to allow your SNMP manager to connect to the IOLAN; this can be done in the DeviceManager, WebManager, CLI, or Menu. You must then load the perle-ds.MIB (found on the CD-ROM packaged with the IOLAN) file into your SNMP manager before you connect to the IOLAN.

Field Descriptions


Secondary Host If the IOLAN cannot communicate with the primary host, then the IOLAN will attempt to send system log messages to this preconfigured host; messages will be displayed on the host’s monitor.Default: None

Level Choose the event level that triggers a syslog entry.Data Options: Emergency, Alert, Critical, Error, Warning, Notice, Info, DebugDefault: Emergency

Note: Ensure that the SNMP service found in the Security, Services page is enabled (by default it is enabled).

Contact The name and contract information of the person who manages this SMNP node.

Location The physical location of the SNMP node.

Community The name of the group that devices and management stations running SNMP belong to. Community only applies to SNMP v1 and v2c.

181

Management

SNMP Traps Tab Field Descriptions


Internet Address The IP address of the SNMP manager that will send requests to the IOLAN. If the address is 0.0.0.0, any SNMP manager with the Community name can access the IOLAN. If you specify a network address, for example 172.16.0.0, any SNMP manager within the local network with the Community name can access the IOLAN.Field Format: IPv4 or IPv6 address

Permissions Permits the IOLAN to respond to SNMP requests.Data Options:

None—There is no response to requests from SNMP.Readonly—Responds only to Read requests from SNMP.Readwrite—Responds to both Read and Write requests from SNMP.

Default: None

Read-Write User Specified user can view and edit SNMP variables.

Read-Only User Specified user can only view SNMP variables.

Trap checkbox Check this box to enable the entry of the trap information.

Internet Address The IP address of the SNMP manager(s) that will receive trap messages from the IOLAN.Field Format: IPv4 or IPv6 address

Version Select the version of trap you want the IOLAN to send.

Type Select between Trap or Inform. Inform requires receiving host to acknowledge receipt of the trap.

182

Management

Custom App/Plugin

OverviewYou can create custom applications for the IOLAN by using the Perle SDK. See the SDK Programmer’s Guide (the SDK and guide are accessible via a request form located on the Perle website at www.perle.com/supportfiles/SDK_Request.shtml) for information about the functions that are supported. You must download the program and any ancillary files to the IOLAN and set the Serial Port Profile to Custom App/Plugin to run a custom application. You must also specify the program executable in the Command Line parameter.A custom application or plugin can be run on the serial port. In this situation, the application will start once the serial port is activated and operate solely on the context of that serial port and any network communications related to that serial port. You could run a different custom application on each serial port. The serial port custom application or plugin is configured by specifying the Custom App/Plugin profile for the serial port.The system level custom application or plugin will begin execution immediately following the system startup. It runs on the context of the whole system and can access network communications as well as any or all serial ports.

Field Description

Community The name of the group that devices and management stations running SNMP belong to. Community only applies to SNMP v1 and v2c.

Inform Timeout This is only used for Inform traps. Select the number of seconds to wait for the acknowledgement of the trap. TDefault: 1 second.

Retires This is only used for Inform traps. Select the number of times the trap will be sent if no acknowledgement is received. Default: 3

V3 Trap User This field identifies the system sending the traps to the host receiving the traps. Same user name is used for all traps sent by this system.

V3 EngineID This is the current Engine ID. The Engine ID is a string which uniquely identifies this SNMP agent.

V3 Use Default EngineID

When this field is selected, the firmware will use the default Engine ID. The de-fault Engine ID uses the MAC address of the Ethernet interface to ensure that the Engine ID is unique to this agent.

V3 Create EngineID Using String

The string entered in this field will be combined with the defined string in hex of 800007AE04 to form the EngineID. Ensure each string is unique for each IOLAN on your network.

Bootup Files Tab Field DescriptionsYou must have a TFTP server running on any host that you are uploading or downloading files to/from. When you specify the file path, the path must be relative to the default path set in your TFTP server software.


Use a Generic WebManager Login Screen

When set, and the user connects to the IOLAN using WebManager, the WebManager login screen that is displayed is generic — the Perle banner, IOLAN model name, and firmware version are not displayed to the user.Default: Disabled

Password Retry Limit

The number of attempts a user is allowed to enter a password for a serial port connection from the network, before the connection is terminated and the user has to attempt to login again. For users logging into the serial port, if this limit is exceeded, the serial port is disabled for 5 minutes. A user with Admin level rights can restart the serial port, bypassing the timeout, by issuing a kill on the disabled serial port. Default: 3

EasyPort Web Select Java if communication is via port 23(Telnet) or port 22(SSH) and communication is not restricted by a firewall.Select Javascript if you need to communicate through a firewall on port 8080 using Easyport.To end and close a Telent session, type CTRL] then quit.To end or close a SSH session, type ~.

Message of the Day (MOTD) Tab Field DescriptionsThe message of the day is displayed when users log into the IOLAN through a telnet or SSH session or through WebManager or EasyPort Web. There are two ways to retrieve the message of the day to be displayed to users when they log into the IOLAN:

The message of the day file is retrieved from a TFPT server every time a user logs into the IOLAN. You must have a TFTP server running on any host that you are uploading or downloading files to/from when using TFTP. When you specify the file path, the path must be relative to the default path set in your TFTP server software. The message of the day file is downloaded to the IOLAN and retrieved locally every time a user logs into the IOLAN. You can download an MOTD file to the IOLAN in the DeviceManager by selecting Tools, Advanced, Custom Files and then selecting the Download Other File option and browse to the MOTD file. In WebManager, select Administration, Custom Files and select the Other File option and browse to the MOTD file. After the MOTD is downloaded to the IOLAN, you must specify the MOTD file name in the Filename field to access it as the message of the day (no TFTP Host parameter is required when the file is internal).


TFTP Host The host that the IOLAN will be getting the Message of the Day file from.Field Format: Resolvable host name, IPv4 address, IPv6 address

Filename The path and file name, relative to the default path of your TFTP server software, of the file that contains a string that is displayed when a user connects to the IOLAN. The IOLAN will look for the file internally (it must already be downloaded), if only the file is specified (no TFTP host) or the file cannot be found on the specified TFTP host.

Display MOTD in WebManager

When enabled, displays the Message of the Day to users who are logging into WebManager. Default: Disabled

186

Management

TFTP Tab Field DescriptionsYou must have a TFTP server running on any host that you are uploading or downloading files to/from.


Note: TFTP file transfers send via UDP packets. When the packet delivery is interrupted for any reason and a timeout occurs, that packet is resent if the retry count allows it. Therefore, if a very large file is being transferred and is interrupted, the entire file is not resent, just the part of the file that was not received.

Retry The number of times the IOLAN will retry to transmit a TPFT packet to/from a host when no response is received. A value of 0 (zero) means that the IOLAN will not attempt a retry should TFTP fail.Range: 0-5Default: 5

Timeout The time, in seconds, that the IOLAN will wait for a successful transmit or receipt of TFTP packets before retrying a TFTP transfer. Range: 3-10Default: 3 seconds

System Administration Chapter 1313
Introduction
This chapter addresses the functions that the admin user or a user with Admin Level privileges might do. This chapter uses the DeviceManager as the configuration method described in most administrative functions. As a general rule, administrative functions are accessed from the menu bar in the DeviceManager and under the Administration option in the WebManager’s navigation tree.

Managing Configuration FilesSaving Configuration Files

When you connect to the IOLAN using either DeviceManager or WebManager, the IOLAN’s active configuration file is loaded into the configurator. To save a backup of the configuration file locally, do the following:

In DeviceManager:1. From the menu bar, select File, Save As. 2. In the Save As dialog box, specify a name and format for the file. Notice that you can save

the file as either a .dme or a .txt file. Either file format can be imported into the DeviceManager and downloaded to the IOLAN in the future. The .dme is a binary file and the .txt file is a text file that can be viewed in any text editor.

3. Click Save.In WebManager:1. In the navigation tree, select the Administration option.2. In the configuration area, click the Backup/Restore button. 3. In the Backup group box, select the format (Binary or Text) in which you want to save the

file. Either file format can be imported into the DeviceManager and downloaded to the IOLAN in the future.

4. Click the Backup Configuration button.


Managing Configuration Files

Downloading Configuration FilesYou can download a configuration file to the IOLAN by doing the following:

In DeviceManager:1. Connect to the IOLAN to retrieve the current configuration file.2. Open the configuration file you want to download to the IOLAN by selecting File, Import

Configuration from a File and then browsing to the configuration file. This will replace the retrieved configuration file.

3. Select Tools, Download Configuration to IOLAN or click the Download All Changes button.

4. Reboot the IOLAN.In WebManager:1. In the navigation tree, select the Administration option.2. In the configuration area, click the Backup/Restore button. 3. In the Restore group box, browse to the configuration file that you want to download to the

IOLAN.4. Click the Restore Configuration button.5. Reboot the IOLAN.

191


Downloading Configuration Files to Multiple IOLANsYou can download a configuration file to multiple IOLANs at the same time by doing the following in DeviceManager (DeviceManager is the only configurator that does this function):1. Select Tools, Download Configuration to Multiple IOLANs.2. Specify the IOLANs that you want to download the configuration to:

Enter the following information for each IOLAN that you want to configure with the same configuration file:

3. Click Add to add the IOLAN to the download list. You can also click on the IOLAN entry and edit any information and then click Update to make the edits permanent.

IP Address Enter the IP address of the IOLAN that you want to download the configuration to.Field Format: IPv4 or IPv6 address

Server Name The name of the IOLAN. The IOLAN name that you put in this field is passed into the configuration before it is downloaded to the IOLAN and cannot be left blank.

Password Enter the admin user password for the IOLAN.

Reboot Server Determines whether or not the IOLAN is rebooted after it has received the new configuration. The new configuration definitions will not go into effect until the IOLAN is rebooted.

192


4. Click the Download> button to start the download process. A status window will display with the configuration download status.

Uploading Configuration FilesWhen you upload a configuration to the DeviceManager, you are uploading the IOLAN’s working configuration file. In most other configurators (the exception being SNMP), you are always seeing the working configuration file.In DeviceManager, select Tools, Upload Configuration from IOLAN. The working configuration file will automatically be loaded into the DeviceManager.

Specifying a Custom Factory Default ConfigurationWhen you receive the IOLAN, it comes with a factory default configuration that the IOLAN can be reset to at any time. Administrators might find it useful to customize the factory default configuration file, so that if the IOLAN gets reset to its factory defaults, it will be reset to defaults that the Administrator specified.There are two ways you can set the custom factory default configuration:

Download a file to the IOLAN—You can download a custom factory default file to the IOLAN using any of the configuration methods. In DeviceManager, you must connect to the IOLAN and then select Tools, Advanced, Custom Files, Custom Factory Default Configuration and then specify the file. In WebManager, you must connect to the IOLAN and then select Administration, Reset, Factory Defaults, Set Current Configuration as Factory Default.Download the current configuration to the IOLAN—You can specify the configuration that you are working with/on as the custom factory default configuration using any of the configuration methods (you must be connected to the IOLAN). In DeviceManager, select Tools, Advanced, Set Factory Default to IOLAN. In WebManager, select Administration, Reset, Factory Defaults, Get and Set Factory Default Configuration File.

193

Downloading IOLAN Firmware

Resetting the IOLAN to the Default ConfigurationThe RESET button on the IOLAN allows you to reset the IOLAN to its Perle or custom factory default configuration. The Power/Ready LED color and the resetting of the IOLAN default configuration vary depending on how long you press and hold the RESET button, as shown in the table below.

Downloading IOLAN FirmwareTo upgrade the IOLAN firmware (software):

In DeviceManager, select Tools, Advanced, Download Firmware to IOLAN. You can browse to the firmware location. Once the firmware download is complete, you will be prompted to reboot the IOLAN. You can choose to reboot the IOLAN at another time by selecting Tools, Reset, Reboot IOLAN. In WebManager, under the Administration option, select Update Firmware. Either browse to the firmware file and then click the Upload button or configure the TFTP server and click the Upload button. Note: If you use the TFTP option, the specified TFTP server must be on the same subnet as the IOLAN.

Upgrading the firmware does not affect the IOLAN’s configuration file or downloaded custom files.

Calibrating I/OAll I/O channels are factory calibrated and should not need recalibration during initial use. However should calibration be required, you can recalibrate in DeviceManager or WebManager. In DeviceManager, you calibrate the I/O channel(s) by selecting Tools, I/O Channels, Calibrate. In WebManager, you calibrate the I/O channel(s) by selecting I/O Channels, Calibrate.

Calibrating Analog InputTo calibrate an Analog input channel, read the section that applies to the type of input you are calibrating. Note that calibration will be done for the active channel configuration; for example, if Channel A1 is set to voltage, you cannot calibrate it for current. The voltage range configured for this channel will also dictate what is being calibrated. For example, if this channel is configured for a range of +/-10V, calibrating this channel will calibrate all channels which are configured for +/-10V. During the calibration process, you will be asked to apply the minimum and maximum configured range value to the channel; for example, to calibrate for voltage +/- 10V, you will be prompted to first apply -10V and then +10V to the channel.Also, you cannot actively calibrate disabled channels (although, for Voltage, if you enable the channel and then set it for a range that has already been calibrated for another channel, it will also be calibrated).

Calibrating I/O

Calibrating VoltageWhen calibrating the IOLAN Analog input for voltage, you will need a calibration meter that is better than .1% volts precision. When you calibrate one channel, all voltage channels are automatically calibrated for that range; if another channel is set for a different range, you will need to calibrate that channel separately, but all channels that use that range are also automatically calibrated.

Calibrating CurrentWhen calibrating the IOLAN Analog input for current, you will need a calibration meter that is better than .1% current precision. Each channel needs to be calibrated individually.

Calibrating Temperature InputTo calibrate an Analog (Temperature) input channel, read the section that applies to the type of input you are calibrating. Note that calibration will be done for the active channel configuration; for example, if Channel A1 is set to thermocouple, you cannot calibrate it for RTD. During the calibration process, you will be asked to apply the minimum and maximum range value to the channel in either mV or Ohms; for example, to calibrate for thermocouple J 0 to 760C, you will be prompted to first apply -80mV and then +80mV to the channel.Also, you cannot actively calibrate disabled channels (although if you enable the channel and then set it for the type of thermocouple or RTD that has already been calibrated on another channel, it will also be calibrated).

Calibrating ThermocoupleWhen calibrating the IOLAN Analog input for thermocouple, you will need a calibration meter that is better than .15% accuracy. When you calibrate one channel, all thermocouple channels are automatically calibrated for that range; if another channel is set for a different range, you will need to calibrate that channel separately, but all channels that use that range are automatically calibrated.

Calibrating RTDWhen calibrating the IOLAN Analog input for RTD, you will need a resistor that is better than .05% Ohms accuracy. When you calibrate one channel, all RTD channels are automatically calibrated for that range; if another channel is set for a different range, you will need to calibrate that channel separately, but all channels that use that range are automatically calibrated.

195

Calibrating I/O

Calibrating Analog ChannelsAnalog Input can be calibrated for Analog and Temperature IOLAN models.

Select the channel you want to calibrate. This example uses an A4 model that has channel A1 set to Current with a Range of 0 to 20mA.If you have not disabled confirmation messages (Tools, Options in DeviceManager only), you will get prompted to verify channel calibration.

Click Yes to proceed with calibration. You are now prompted to apply 0 mA to the positive (+) and negative (-) terminals. Once that is done, click Yes to proceed.

You are now prompted to apply 20 mA to the positive (+) and negative (-) terminals. Once that is done, click Yes to proceed.

Once calibration is successfully completed, click OK to finish the process.

Resetting Calibration DataYou can reset the I/O channels calibrations to the factory calibrations in DeviceManager by selecting Tools, I/O Channels, Reset Calibrate Data or in WebManager by selecting Administration, Reset, I/O Calibration.

196

Setting the IOLAN’s Date and Time

Setting the IOLAN’s Date and TimeWhen you set the IOLAN’s time, the connection method and time zone settings can affect the actual internal clock time that is being set. For example, if you are connecting to the IOLAN through the DeviceManager and your PC’s time zone is set to Pacific Standard Time (GMT -8:00) and the IOLAN’s time zone is set to Eastern Standard Time (GMT -5:00), the IOLAN’s time is actually three hours ahead of your PC’s time. Therefore, if you set the IOLAN’s time to 2:30 pm in the DeviceManager, the IOLAN’s actual internal clock time is 5:30 pm. This is the only configuration method that interprets the time and converts it between time zones, as necessary.All other configuration methods set the IOLAN’s internal clock time to the time specified, with no interpretation.To set the IOLAN’s system clock in DeviceManager, select Tools, Advanced, Set Unit Time/Date. The Set Date/Time window is displayed.


Rebooting the IOLANWhen you download any file (configuration, keys, certificates, firmware, etc.) to the IOLAN, you must reboot the IOLAN for it to take effect by selecting Tools, Reset, Reboot Server in DeviceManager and Administration, Reboot Unit in WebManager.

Resetting the Serial Port StatisticsYou can reset the IOLAN’s serial port statistics back to zero.

Note: IOLAN DS1 and TS2 models do not retain the date/time settings when the unit is rebooted.

Date The IOLAN’s date. The format of the IOLAN’s date is dependent on the Windows operating system and regional settings.

Time The IOLAN’s internal clock time, based on your PC’s time zone. For example, if your PC’s time zone is set to Pacific Standard Time (GMT -8:00) and the IOLAN’s time zone is set to Eastern Standard Time (GMT -5:00), the IOLAN’s time is three hours ahead of your PC’s time. If you set the IOLAN’s time to 2:30 pm, the IOLAN’s actual internal clock time is 5:30 pm.

Use the PCs Date/Time

When enabled, sets the IOLAN’s time to the PCs time.Default: Enabled

This option is unique to the DeviceManager.

197

Resetting the IOLAN to Factory Defaults

Resetting the IOLAN to Factory DefaultsYou can reset the IOLAN to its factory default configuration by selecting Tools, Reset, Reset to Factory Default in DeviceManager and Administration, Reset, Factory Defaults in WebManager. The IOLAN will automatically reboot itself with the Perle factory default or custom factory default configuration.

Language SupportTwo language files, in addition to English, are supplied on the supplemental CD, French and German. You can use any of these language files to create a translation into a language of your choice. You can download the language file (whether the language is supplied or translated) into the IOLAN and select the Language option of Custom Language or Customlang (custom language), making the Menu and CLI field labels display in the desired language.You can view Menu or CLI in one other language only (as well as English). If you download another language file, this new language will replace the first language you downloaded.You can revert to English at any time; the English language is stored permanently in the IOLAN and is not overwritten by your new language. Each user logged into the IOLAN can operate in either English or the downloaded language.

Loading a Supplied LanguageThis section describes how to download a language file using the CLI, since it is the least intuitive method. French and German language files are provided on the supplemental CD.To load one of the supplied languages into the IOLAN, so the Menu or CLI fields appear in another language, do the following:1. Open the supplemental CD and identify the language file, either Iolan_ds_French.txt or

Iolan_ds_German.txt, or supply one of your own translated files.2. Copy the language file to a host machine on the network; place it in the main file system or on

the main hard drive.3. Either use the TFTP defaults in the IOLAN or, configure as necessary, TFTP in the IOLAN.4. In the CLI of the IOLAN, enter the host IP address and file name; for example,

netload customlang 172.16.4.1 /temp/Iolan_ds_French.txt

The IOLAN will download the language file via TFTP.In DeviceManager select Tools, Advanced, Custom Files and then select Download Custom Language File and browse to the language file. In WebManager select Administration, Custom Files and then specify the Custom Language File option and browse to the language file.

5. To set an individual user to the new language, go to the Users menu and, in the Language field select Customlang. In the CLI (only) you can set individual users or all users to the new language; see the set user * command.

6. The user will see the change of language when he/she logs out (Main Menu, Sessions Menu, Logout) and logs back into the IOLAN. If, as Admin user, you change your language setting to Customlang, you will see the text menus display in the new language when you save and exit the Change User form. Users with Level Normal can also change their display language.

Note: If you download a new software version, you can continue to use your language unchanged; however, we recommend translating the new strings, which will be added to the end of the language file. A Reset to Factory Defaults will reload the Customlang as English. On successful download, the Customlang in the IOLAN will be overwritten by the new language.

198

Language Support

Translation GuidanceTo help you with your translation, of supplied ASCII text language files we offer the following guidance:

The IOLAN will support languages other than English (and the supplied German and French languages). The English language file, english.txt, displays the character length of each line at the beginning of the line. If a translated line goes over that character length, it will be displayed truncated in the Menu or CLI.Translate line for line, do not omit lines if you do not know the translation; leave the original untranslated text in place. Also, you must maintain the same sequential order of lines. It is a good practice to translate the file using a text editor that displays line numbers, so you can periodically verify that the line sequence has not changed from the original file (by comparing it to the original file).Keep all translations in quotes, otherwise the line will not display properly. Each line must end with a carriage return.If a line contains only numbers, for example 38400, leave that line in place, unchanged (unless you are using a different alphabet).

Software Upgrades and Language FilesIf you receive a software upgrade for the IOLAN, the language files supplied on the supplemental diskette/CD might also have been updated. We will endeavour to provide a list of those changes in another text file on the same supplemental CD.

If you are already using one of the supplied languages, French or German, you probably want to update the language file in the IOLAN. Until you update the IOLAN with the new language file, new text strings will appear in English.If you are already using a language translated from an earlier version, you probably want to amend your translation. When a language file is updated, we will try to maintain the following convention:1. New text strings will be added to the bottom of the file (not inserted into the body of the existing

file).2. Existing text strings, if altered, will be altered in sequence; that is, in their current position in the

file.3. The existing sequence of lines will be unchanged.4. Until you have the changes translated, new text strings will appear in the Menu or CLI in

English.

Note: The upgrade of your software (firmware) will not change the display of the language in the Menu or CLI.

Downloading Terminal Definitions

Downloading Terminal DefinitionsAll terminal types can be used on the IOLAN. Some terminal types which are not already defined in the IOLAN, however, are unable to use Full Screen mode (menus) and may not be able to page through sessions properly. When installed, the IOLAN has several defined terminal types—Dumb, WYSE60, VT100, ANSI, TVI925, IBM3151, VT320-7, and HP700/44.If you are not using, or cannot emulate, any of these terminal types, you can add up to three additional terminal definitions to the IOLAN. The terminal definitions can be downloaded from a TCP/IP host.To download terminal definitions, follow these steps:1. Decide which TCP/IP host you are going to use. It must be a machine with enabled.2. Configure TFTP in the IOLAN as necessary.3. Select Tools, Advanced, Custom Files from the menu bar.4. From the File Type drop-down, select Download Terminal Definition. Select the terminal

definition option 1, 2, or 3 and then browse to the terminal definition file that is being downloaded to the IOLAN.

5. In the Terminal profile, select the Terminal Type Termx that you custom defined.

Creating Terminal Definition FilesTo create new terminal definition files, you need to copy and edit the information from the terminfo database.1. On a UNIX host, change directory to /usr/lib/terminfo/x (where x is the first letter of the

required terminal type). For a Wyse60, for example, you would enter the command cd /usr/lib/terminfo/w.

2. The termcap files are compiled, so use the command infocmp termfile to read the required file (for example: infocmp wy60).

3. Check the file for the attribute xmc#n (where n is greater than or equal to 1). This attribute will corrupt menu and form displays making the terminal type unsuitable for using Menu mode.

4. If the terminal definition is suitable, change to a directory of your choice.5. Rename and copy the file to the directory specified at step 4. using the command

infocmp termfile > termn where n is greater than or equal to 1; (for example, infocmp wy50 > term1). Make sure the file has global read and execute permission for its entire path.

6. Edit the file to include the following capabilities in this format:

term=acsc=bold=civis=clear=cnorm=cup=rev=rmacs=rmso=smacs=smso=page=circ=

Resetting Configuration Parameters

For example:

Resetting Configuration ParametersYou can reset the IOLAN to its factory default settings (this will reset it to the original factory default or custom factory default settings, depending on what has been configured) through any of the following methods:

You can push in the recessed button at the back of the IOLAN hardware for three to ten seconds (pushing it in and then quickly releasing will just reboot the IOLAN)DeviceManager, select Tools, Reset, Reset to Factory DefaultsCLI, at the command line type, reset factoryWebManager, select Administration, Reset, Factory Default, and then click the Reset to Factory Defaults buttonMenu, select Network Configuration, Reset to Factory DefaultsSNMP, in the adminInfo folder, Set the adminFunction variable to 2

Note: As you can see from the example, capabilities which are not defined in the terminfo file must still be included (albeit with no value). Each entry has an 80 character limit. On some versions of UNIX, some of the capabilities are appended with a millisecond delay (of the form $<n>). These are ignored by the IOLAN and can be left out. The ‘acsc’ capability, if defined, contains a list of character pairs. These pairs map the characters used by the terminal for graphics characters to those of the standard (VT100) character set. Include only the following character pairs: jx, kx, lx, mx, qx, tx, ux and xx (where x must be substituted by the character used by the terminal). These are the box-drawing characters used to display the forms and menus of Menu mode. They must be entered in this order. The last two capabilities will not be found in the terminfo file. In the page field you must enter the escape sequence used by the terminal to change screens. The circ field defines whether the terminal can use previous page and next page control sequences. It must be set to y or n. These capabilities can be found in the documentation supplied with the terminal.

Virtual Modem AT Commands Appendix AA

Virtual Modem Initialization Commands

You can initialize the modem connection using any of the following commands:

Note: Virtual Modem initialization commands are only supported on IOLAN firmware and configurators version 3.2 or higher.

Command Description Options

ATQn Quite mode. Determines if result codes will be sent to the connected terminal. Basic results codes are OK, CONNECT, RING, NO CARRIER, and ERROR.Setting quite mode also suppresses the "RING" message for incoming calls.

n=0, no result codes will be sent.n=1, result codes will be sent. (default)

ATVn Verbose mode. Determines if result codes are displayed as text or numeric values.

n=0, display as numeric values.n=1, display as text. (default)

ATEn Echo mode. Determines whether characters sent from the serial device will be echoed back by the IOLAN when VModem is in "command" mode.

n=0, disable echo.n=1, enable echo. (default)

+++ATH Hang up. This command instructs the IOLAN to terminate the current session and go into "command" mode.

ATA Answer call. Instructs the VModem to accept connection requests. VModem will give the terminal up to 3 minutes to answer the call. If the ATA is not received within 3 minutes, all pending sync messages will be discarded.

ATI0 Return the modem manufacturer name.

ATI3 Return the modem model name.

ATS0 Sets the value of the S0 register. The S0 register controls the "auto answer" behavior.In "manual" mode, the IOLAN will not accept incoming sessions until an ATA is issued by the serial device. In "auto answer" mode, the IOLAN will automatically accept an incoming connection request.

Register=0, sets "manual answer" modeRegister=1-255, "auto answer" mode (default)


Virtual Modem Initialization Commands

AT&Z1 Set command allows the user to store an IP address and port number or phone number to use when making a connection. The user will issue an ATDS1 to cause the IOLAN to initiate the connection.

AT&Sn Sets the behavior of IOLAN’s DTR signal. (DSR from a DCE perspective)

n=0, DTR signal always high. (default)n=2, DTR signal acts as DCD. n=3, DTR signal acts as RI.

AT&Rn Sets the behavior of IOLAN’s RTS signal. (CTS from a DCE perspective)If line is configured for hardware flow control, the RTS is used for this purpose and the setting of this command is ignored.

n=0, RTS always high. (default).n=3, RTS signal acts as DCD.n=4, RTS signal acts as RI.

AT&Cn Sets the behaviour of the DCD signal. n=0, DCD always on.n=1, DCD follows state of connection (off when no connection, on when TCP connection exists). (default)

AT&F Sets the modes back to the factory defaults. This is a hard-coded default configuration which does not look at any user configuration.

ATS2 Sets the value of the S2 register. The S2 register controls which character is used to enter "command" mode. (this is the potential replacement for the +++ (default) in front of the ATH command).This register will hold the hex value of the "escape" character. Any value > 27 will disable the ability to escape into "command" mode.

ATS12 Sets the value of the S12 register. The S12 register controls the minimum length of idle time which must elapse between the receipt of the escape character and the A (first character of the ATH sequence). Units are 1/50th of a second. The default is 50 = 1 second.

ATO (ATD with no phone number) Establishes a connection using the IP and port specified in the telephone number field.

ATDS1 Establishes a connection using the IP and port (or phone number) specified in the Phone Number field (stored by the AT&Z1 command).

Setting Jumpers Appendix CC
Introduction
The IOLAN contains jumpers that you might need to set before you configure it and put it into production. You can set the IOLAN line termination to on or off (this is off by default) if you are using EIA-422/485 (not applicable for I/O models).

1-Port IOLAN

TruePort Utility Appendix EE
Introduction
This chapter provides information on the TruePort utility.

TruePortTruePort is a com port redirector utility for the IOLAN. It can be run in two modes:

TruePort Full mode—This mode allows complete device control and operates exactly like a directly connected serial port. It provides a complete COM port interface between the attached serial device and the network.TruePort Lite mode—This mode provides a simple raw data interface between the device and the network. Although the port will still operate as a COM port, control signals are ignored. In this mode, the serial communications parameters must be configured on the IOLAN.

You use TruePort when you want to connect extra terminals to a server using the IOLAN rather than a multi-port serial card. When run on UNIX, TruePort allows you to print directly from a terminal to an attached printer (transparent printing). You can also remap the slow baud rate of your UNIX server to a faster baud rate, as shown below.

Currently, TruePort is supported on Linux®, Windows®, SCO®, Solaris®, and others. For a complete list of supported operating systems, see the Perle website.For more information, see the TruePort User Guide.

API I/O Access Over TruePort

API I/O Access Over TruePortYou can access IOLAN I/O data through TruePort using the Perle API. The API uses the command/response format. See the ioapiotp.c sample program, found on the product CD-ROM, for an example implementation.

API Request FormatAll data in the Request must be sent as a single write to the COM port. The API command takes the following format:

API Response FormatThe API command takes the following response format:

Number of Bytes Value

1 Function Code (in hex):01—Get read/write boolean register03—Get read/write register04—Get read only register15—Set read/write boolean register (0x0F)16—Set read/write register (0x10)

2 Starting register number (see A4/T4 Registers , A4D2/A4R2 Registers , or D4/D2R2 Registers for this value).

2 Number of registers to act on starting from the register defined in byte 2 above.

n Data for write. Some values must be read/written as a unit consisting of 2 consecutive registers. If the request is to write, the data to write follows the number of registers. If accessing registers consisting of 2 bytes or 4 bytes, the data is in big endian (network order) format.

Number of Bytes Value

1 Function code of request if no error. Most significant bit will be set if an error occurred.

1 Length of data in response if no error occurred. If an error occurred, the byte will contain the error code (see the Error Codes table below).

n Data response for request (the number of bytes is dependent on the number and type of registers requested). If the request returns 2 or 4 byte values, it will be in big endian (network order) format. If the request returns boolean values, the least significant bit (bit 0) represents the first value requested and bits 1 to 7 represents subsequent boolean values. If more than 8 boolean registers are requested, they are returned in successive bytes.

Troubleshooting Appendix GG
Introduction
This chapter provides information that can help resolve problems with the IOLAN.

Hardware ProblemsThe IOLAN Power/Ready LED is red and stays red for over 10 seconds.You have a hardware problem that might require factory service. First, try the following:

If the IOLAN is not in Console mode, do the following:a. Set up a direct connection to the IOLAN; see Through the Serial Port for information on

this type of connection.b. Power the IOLAN off.c. Switch the Console dip switch to On.d. Power the IOLAN on. If there is a problem with the IOLAN firmware, you will need to reload the firmware, which can be found either on the CD-ROM that came with the IOLAN or on the Perle website, www.perle.com/downloads (when you access the webpage, select your specific IOLAN model).If the IOLAN is already in Console mode and the Power LED stays red, you need to make arrangements to return the IOLAN.

If you purchased the IOLAN less than 30 days before this problem appears, contact your distributor; otherwise, see the Perle web site (www.Perle.com) for factory service information. Note: no factory service can be performed on IOLANs that have not been registered.The Power/Ready LED continues to blink green in desktop models.This is not an error, the Power/Ready LED will blink green when serial port 1 is in Console Mode.

Communication IssuesGeneral communication checks and practices are as follows:

Are your cables connected and correctly configured? If you are using EIA-232, see EIA-232 Cabling Diagrams to verify that your cables are correctly configured.Can you ping your host? If you can ping but packet loss is reported, ping another host/device on the same network. This will tell you whether the problem is specific to the host/device or general to the network.After entering or changing IP information for your IOLAN, reboot the IOLAN (does not apply when using BOOTP or DHCP). Once the IOLAN has rebooted, other network devices should be able to communicate with it (ping, telnet, etc.). Also, protocols such as ARP and proxy-ARP will work properly.

DeviceManager Problems

Use the show routes command (command line only) or view the Routes statistics. Is there a route to the host?If the WebManager or DeviceManager cannot communicate with the IOLAN, verify that the Security, Services HTTP parameter is enabled for WebManager and DeviceManagerD is enabled for DeviceManager.

DeviceManager ProblemsError Message: 16 bit Windows Subsystem - C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application.The error message can be misleading, because it is displayed even if the AUTOEXEC.NT file is actually missing.To verify whether you have the file, type %windir%/system32/ in the address bar of an Explorer window. If there is no AUTOEXEC.NT file proceed as follows: 1. Browse to %windir%/repair/ (usually C:\WINDOWS\repair).2. Right-click and Copy the AUTOEXEC.NT file.3. Browse to %windir%/system32/ (usually C:\WINDOWS\System32).4. Right-click inside the window and Paste the file.The error condition described here may also be the result of corruption of the AUTOEXEC.NT file, in which case the above procedure may be helpful to restore a valid file.If the above procedure does not fix the DeviceManager installation problem, see http://support.microsoft.com/?kbid=324767 for the official Microsoft explanation.

Host ProblemsCannot access a host on a local network, verify:

The network address is correct.The subnet mask is set correctly and reflects the network configuration.The broadcast address is set correctly and reflects the network configuration.

Cannot access a host on a remote network:Use the show route command to verify that there is a route to the remote host. If no gateway is specified, verify that a default gateway is specified. Ping the default gateway to check if it is working.Consider the situation beyond the gateway; for example, are intermediate gateways and the remote host available? Also, check the messages returned by the ping command; for example, that a particular host or gateway is unreachable.

Gateways added into the gateway table are ignored by the IOLAN:Have you used BOOTP and entered a single static gateway in the bootptab file entry? If yes, the other gateways will be ignored.

Access to host lost after a few minutes.If the route to this host goes through routers, make sure those routers are all sending RIP packets across the networks.

Login ProblemsYou have lost or don't know your password (as admin user).

234

http://support.microsoft.com/?kbid=324767

Problems with Terminals

You must reset the IOLAN to its factory default settings using the Reset switch on the rear panel. There is no procedure to access the IOLAN without a password.

Problems with TerminalsThe following section concerns problems with the appearance of data on your terminal screen.The IOLAN logs me out after a few minutes:

Check the Idle Timer value set for the user. The default setting for the Idle Timer for all users is 0 seconds (does not timeout).

Corrupt data.Check your line settings (baud rate, stop bits, etc.)

Missing data.Verify that the same type of flow control is set in both your terminal and on the IOLAN’s port.

Error message not permitted on a dumb terminal after typing the CLI command screen.

Set your Line to Termtype VT100, ANSI or WYSE60 (or other form of terminal emulation, if you have downloaded one). The default line type in the IOLAN is Dumb, which does not support the graphics characters necessary to view the text-based menus.

Screen corruption when using the text-based menu system.Verify that the terminal setup in the IOLAN matches your terminal.Verify that entries in the term file match your terminal setup.If using a PC/computer, verify that the type of terminal emulation selected in your application matches those supported by the IOLAN.

When using the function keys on your keyboard, nothing happens or your sessions keep swapping.

Change your Hotkey Prefix character. The function keys on the keyboards of some terminals (like WYSE60) send character sequences which begin with ^a; unfortunately, ^a is also the default Hotkey Prefix, which you use to switch between sessions. A valid alternative would be ^b (hex=02). If you are the system administrator, you can change any user’s Hotkey Prefix character.

When using a downloaded terminal definition, you are having problems using arrow keys.Use Ctrl-K, Ctrl-J, Ctrl-H and Ctrl-L for up, down, left and right respectively.

When switching from a session back to the text menus, both screen images are superimposed. Press ^r to redraw the screen.

INIT: Error in terminal file <filename>This error indicates that you have exceeded the 80 character limit for one or more of the terminal capabilities defined in the reported file.

INIT: Error on line n in terminal file <filename>You have omitted the = sign from the reported line.

Unknown IP AddressYou have already configured the IOLAN and you do know your password, but have lost, misconfigured, or don't know the IP address of the IOLAN, and you cannot obtain a login.

If the IOLAN resides within the local network segment, you can use DeviceManager to find the IOLAN.You can connect directly to the serial port of the IOLAN, as explained in Through the Serial Port .

235

DHCP/BOOTP Problems

DHCP/BOOTP ProblemsMessages: host name too long or filename too long.

The IOLAN can only accept host names of 14 characters or file names of 64 characters, so verify that you are not attempting to pass a string that is longer than those maximums.

DHCP or BOOTP have been set up to configure my IOLAN, but does not seem to have done anything.

Check that the server DHCP/BOOTP service is set to on, if not set it to on and reboot.Check that your BOOTP server is configured for your IOLAN or that your DHCP server has an active lease pool (scope) with at least 1 free IP address.

You observe TFTP errors when the IOLAN boots, for example:TFTP: File not found : filename

TFTP: Timed out

This has a number of causes, including:The file names you specified to DHCP/BOOTP do not exist or are in the wrong place.The server for any of the downloadable files in your bootfile has no TFTP server running.Verify that lease data in your DHCP server manager is correct.Reset or restart the DHCP server.

Language ProblemsIn a customized language, the text strings appear in the wrong place in the Menu or CLI.

Check the original ASCII text file you used to translate to your customised language. The sequence of the line much match exactly (be aware that comments don’t affect line sequence, but can affect the actual line that the strings appear on). So, if you strip out all comments, if the original file says line 1000 should be string none, then line 1000 (stripped of comments) should be the translated version of none.

Long Reboot CycleRebooting the IOLAN takes a long time.If you are not using DHCP/BOOTP, disable this within the Server Services; otherwise, the IOLAN waits to timeout for a request to DHCP/BOOTP.

I/O ModelsAn I/O Digital or Relay controlled motor is starting/stopping

Digital and Relay channels have automatically resetting fuses, meaning that if the circuit gets overloaded and the fuse blows, it will automatically reset when the circuit cools down.

An A4R2 model is starting/stoppingThe A4R2 model can run at 55 degrees Celsius ambient temperature when the input voltage is 22VDC or below. If the input voltage exceeds 22VDC, the maximum ambient temperature will drop into the range of 45-50 degrees Celsius to run successfully.

236

IPv6 Issues

IPv6 IssuesYou are not seeing the IPv6 address value when you attempt to connect to the IOLAN.Many Windows based systems have IPv6 support already enabled, however, if you need to install IPv6 then follow the procedure below.To install IPv6 support in Windows® do the following:1. In Control Panel, double-click the Network Connections icon.2. Double-click the Local Area Connection entry.3. In the Local Area Connection Status window, click the Properties button on the General tab.4. In the Local Area Connections window, click the Install button on the General tab.5. In the Select Network Component Type window, select Protocol and click the Add button.6. In the Select Network Protocol window, select Microsoft TCP/IP version 6 and click the OK

Modbus Remapping Appendix II
Introduction
This appendix provides additional information about the Modbus Remapping feature.

Modbus Remapping FeatureThe Modbus remapping feature allows a TCP Modbus Master to poll a Modbus slave device and have the IOLAN translate the UID to a different UID for the slave device. The Master UID has to be unique on the IOLAN. The Slave UID must be unique on each serial port. The translate rules are controlled by a file downloaded to the IOLAN.

The following procedure will allow you to use the Modbus remapping feature:

Create a configuration fileThe file must be called "modbus_remap"One translate rule per lineThe fields on a line are separated by a comma

Line format for one UID is: port,master_uid,slave_uid

port: is the IOLAN port number that the slave is connected tomaster_uid: is the UID that the TCP Modbus Master usesslave_uid: is the UID that the Modbus slave uses

Line format for UID ranges is: port,master_start-master_end,slave_start-slave_end

port: is the IOLAN port number that the slave is connected tomaster_start: is the first master UID in the rangemaster_end: is the last master UID in the rangeslave_start: is the first slave UID in the rangeslave_end: is the last slave UID in the range

Configuring the Modbus UID Translation Feature1. On the serial port Modbus Gateway, configure Modbus slave. Configuration parameters such as

“UID range” and UID Address Mode will be ignored in this mode of operation

Glossary

This chapter provides definitions for Device Server terms.

BOOTP (BOOTstrap Protocol)

An Internet protocol that enables a diskless workstation to discover its own IP address, the IP address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the workstation to boot without requiring a hard or floppy disk drive.

Community (SNMP) An SNMP community is the group that devices and management stations running SNMP belong to. It helps define where information is sent.

DHCP (Dynamic Host Configuration Protocol)

A TCP/IP protocol that provides static and dynamic address allocation and management.

Direct Connection Connections that bypass the Device Server enabling the user to log straight into a specific host. A direct connection is recommended where a user logging in to the Device Server is not required.

Ethernet A high-speed (10Mbps,100Mbps) cable technology that connects devices to a LAN, using one or more sets of communication protocols.

Fixed Callback A method where there is a specific number defined to callback a user.

Local Authentication Uses the user ID and password stored within the Device Server User database.

LPD Line Printer Daemon. A printer protocol that uses TCP/IP to establish connections between printers and workstations on a network. The technology was developed originally for BSD UNIX and has since become the de facto cross-platform printing protocol.

Modem Initialization String

A series of commands sent to the modem by a communications program at start up. These commands tell a modem how to set itself up in order to communicate easily with another modem.

MOTD Message of the day. This is defined by a file whose contents display when users log into the Device Server.

Multicast The broadcasting of messages to a specified group of workstations on a LAN, WAN, or internet.

NAK (Negative Acknowledgment)

A communication control character sent by the receiving destination indicating that the last message was not received correctly.

RADIUS (Remote Authentication Dial In Users Services)

An open standard network security server that communicates with the PAP protocol.

Reverse Connection Connections that originate from a host that go directly to a serial device through the Device Server.

RIP (Routing Information Protocol)

A protocol that allows gateways and hosts to exchange information about various routes to different networks.


Roaming Callback A method where the client supplies the number for callback when they dial in.

RPC Remote Procedure Call. A type of protocol that allows a program on one computer to execute a program on a server computer.

Silent Connection Silent connections are the same as direct connections except that they are permanently established. The host login prompt is displayed on the screen. Logging out redisplays this prompt. Silent connections, unlike direct connections, however, make permanent use of pseudo tty resources and therefore consume host resources even when not in use.

SNMP (Simple Network Management Protocol)

A protocol for managing network devices.

Subnet/Prefix Bits Identifies the device’s IP address, which portion constitutes the network address and which portion constitutes the host address.
